November 2007: TOF-MS components for Open University, UK
We are supplying various components to Dr. Sam Eden of the Open University to allow him to assemble a time-of-flight mass spectrometer system. Dr. Eden will be ionising monomer and cluster species using pulsed laser, electron or ion beams. The detection system will be based on a 10kV post-accelerated conversion dynode with a separated electron multiplier, to enhance the conversion efficiency of cluster species.
October 2007: TOF-MS components for University of Leuven, Belgium
We are supplying various components to Dr. Jorg DeHaeck of the Department of Solid Sate Physics and Magnetism at the University of Leuven in Belgium to allow him to build a high mass resolution time-of-flight instrument for studying large clusters. This high-resolution instrument will fit onto an existing binary cluster laser ablation source and will be used for detection, photo-fragmentation and photo-electron spectrometry of neutral, positive and negative charged clusters up to 250,000 amu.
Dr. DeHaeck has ordered high specification reflectrons on purpose-built tilting flanges, a DMCP detector, pre-amplifier and data acquisition chain (fast TDC, computer, acquisition software), and also a high precision motorised tilting stage onto which he will be mounting his own design of TOF source for creating pulses of ions.
October 2007: TOF-MS system for Russian Academy of Sciences, Moscow
We are pleased to announce that we are building a compact add-on time of flight analyser for the Russian Academy of Sciences to allow the characterisation of species ablated at very high temperatures from oxide surfaces using pulsed lasers. Dr. Mike Sheindlin has worked with Kore to define an instrument that can be added onto an experimental chamber and will allow him to pass a 'spotting' (guide) laser through our ion optics to indicate the location of the main laser ablation spot. The main laser will ablate material from a sample directly beneath a skimmer cone, inside which is an electron impact ioniser. Ions created by the EI source are then extracted into the TOF-MS for subsequent mass analysis.
September 2007: Moving and refurbishing surface analysis instruments
We have recently moved and refurbished surface analysis instruments on the new National Physical Laboratory Campus. There seems to be an increase in this type of project this year, because we have also moved instruments on the Heriot-Watt campus as well from Sheffield University and Loughborough Surface Analysis.
Kore is uniquely qualified to assist clients in research institutes who wish to re-locate large multi-chamber UHV surface analysis instruments. Typically these systems tend to be quite old with a variety of modules from various manufacturers and it is usually necessary for us not only to move but also to modestly refurbish these instruments. It is generally more environmentally friendly and cost effective to refurbished such instruments, rather than consigning them to scrap, as they will have many years of useful service left in them.
August 2007: PTRMS for FAB plant
We have successfully installed a Proton Transfer Reaction TOF Mass Spectrometer in a major FAB facility to measure VOCs in semiconductor wafers. PTR sources selectively ionise VOCs from atmospheric pressure gas streams without ionising the major constituents of air. These ion sources use H3O+ ions to transfer a proton to the atmospheric stream, "soft" ionising the analyte molecules and thus minimising the fragmentation of these molecules. Contamination control engineers in FAB plants wish to extend the speed and sensitivity when detecting contaminants. The parallel detection capabilities of TOF-MS are very attractive from this point of view compared to using a sequential (scanning) mass spectrometer.
July 2007: MS200 portable mass spectrometer used as an educational aid
We are pleased to announce the sale of an MS200 portable time-of-flight mass spectrometer to the University of Leicester to assist in the teaching of chemistry and mass spectrometry to students in the university and surrounding high schools. The MS200 has already been used as a teaching aid not only in high schools but also in primary schools in the Cambridgeshire region. The MS200's rapid acquisition of mass spectra permits the demonstrator to discuss the basis ideas of a "chemical signature" and the identification of compounds via molecular masses and fragment patterns.
June 2007: New SurfaceSeer Demonstration Facility
Our client at Innovia has kindly agreed to run demo samples for us on their TOF-SIMS surface analyser-The Kore SurfaceSeer instrument. Because Innovia are an industrial company using the instrument regularly for their own work, we have limited access and therefore we must limit the number of samples we can run free-of-charge. However, even running two samples should allow you to see the type of data that the instrument produces. Details on how to have a sample run can be found on the SurfaceSeer page.
April 2007: Used liquid metal ion gun (LMIG) available
From time-to-time we acquire equipment from used systems that we have built or supported. Recently, we acquired a working FEI 25KV two-lens Gallium liquid metal ion gun (LMIG) and its power supplies that were part of a TOF-SIMS chemical imaging system. This gun could be used in any application requiring a bright, fine focus, continuous or pulsed (to <10ns) ion beam. This source has now been successfully incorporated into a custom system for a client
November 2006: Affordable TOFSIMS
We are pleased to announce that we have completed the design, build and delivery of a new, 'affordable' TOF-SIMS instrument for one of the world's leading manufacturers of complex, multi-layered polymer films.
Detailed knowledge of the surface chemistry of these films is essential for their manufacture and subsequent surface treatment processes such as printing, etc. In relation to the quality of their products the client has been aware of the benefits of surface analysis for a long time, and has been sending samples out to one of the U.K.'s commercial analytical labs. However, as a forward-thinking company, there has been an increasing desire to incorporate TOF-SIMS analysis as part of the fundamental product verification within the company. The company thus faced the prospects either of increased external services costs or the almost impossible task of justifying £750k for a commercial TOF-SIMS instrument.
That's when the client came to Kore. Initially they were intrigued by the possibility of the MS-1000 instrument, although after discussions it became clear that this instrument would not be appropriate, since it does not offer a negative SIMS capability. Accordingly, Kore decided once again to tackle the issue of how to manufacture a TOF-SIMS instrument at an affordable price of <£150k. For this client, it was absolutely essential that the instrument perform effortlessly on insulators, since that is the client's only sample type.
The result is an exciting new instrument development that really does offer easy sample analysis by TOF-SIMS on insulators at an affordable price for this type of surface analysis instrumentation. We will be posting much more detail about the instrument very soon, with photographs, designs and data.
September 2006: High Performance imaging/depth profiling TOFSIMS
We are pleased to announce that we completed the design, build and delivery of a complex, high performance TOF-SIMS system customised for a U.S. government laboratory's application requirements. The system has a liquid metal ion gun for sub-micron high spatial resolution SIMS imaging. This beam is also 'bunched' to provide the ultra-short primary pulses required for high mass resolution in TOF- SIMS. A second primary beam, from a low energy gas ion source, can be interleaved at high frequency with the pulsing liquid metal ions to permit sample depth profiling. Samples enter via a fast entry lock and can then be processed in an extensive preparation chamber with multiple sample heating/cooling and deposition facilities. In the main analysis chamber there is provision for expansion to include XPS and laser beam post ionisation of neutrals as well as further sample conditioning. Complete data processing software was also provided to make this a complete system designed built and tested by Kore to meet the client's requirements.
August 2006: Combined Cassegrain / Ion Optics and Mini Tof MS
We are pleased to have received an order from a German research group within the chemical company BASF. The researchers will ionise adsorbed gases on sample surfaces using a multi-photon laser, and then measure the mass of the liberated ions. For effective ionisation, the laser needs to be tightly focused and so we are supplying our Cassegrain optics combined with our Mini Tof MS to make a fully integrated system.
July 2006: Multiple Complex Components manufacture
The majority of Kore's business is designing and manufacturing customised analytical instruments for researchers around the world. However we have recently completed a project delivering over 250 identical components to a major Defence Contractor.
Kore won the order by demonstrating success with prototype components, using our extensive knowledge of vacuum sealing techniques in a novel combination with hydraulics, as well as our demonstrated ability to manage small projects efficiently and with low overheads. For this project we developed new testing techniques that allowed us an eventual yield rate of more than 99%. The components were all delivered to a tight quality specification and within the client's requested timescale.
June 2006: PTR-MS sources
We are pleased to announce that we have taken two more orders for our new proton transfer reactor source, one from the university of York in the U.K., and one from the Université de Paris Sud in France. The ion source has been designed from first principles using high pressure ion modelling developed in-house to achieve a high current of Hydronium ions (H3O+). A primary beam of 25pA is guaranteed from the source (1.5 x 108 ions/sec).
The researchers will be coupling these sources to their mass spectrometers to selectively ionise VOCs from atmospheric pressure gas streams without ionising the major constituents of air. These ion sources use H3O+ ions to transfer a proton to the atmospheric stream, "soft" ionising the analyte molecules and thus minimising the fragmentation of these molecules. Further details about chemical ionisation by proton transfer can be found here.
September 2005: Kore collaborates with Japanese venture incubator company TSI
Kore has recently signed a collaboration agreement with the Technology Seed Incubation Co., Ltd. (TSI) in Kyoto, Japan. TSI's capabilities will be useful when local support is required for Kore's Japanese Design-for-Research projects. Similarly Kore's capabilities will be utilised for some of TSI's venture company's product's designs. TSI is part of the Japan Asian Investment Corporation's (JAIC) incubation facilities in Asia. JAIC is a primary investor in Kore's associated venture analysis company Yuno ltd, on whose website more information can be obtained about JAIC and TSI.
June 2005: New Research PTR/APCI TOF-MS for Nottingham University's Division of Food Science
We are pleased to announce that we have received an order for a new TOF-MS instrument designed to allow researchers at Nottingham University's Division of Food Science to extend the detection sensitivity of flavour molecules in real- time. Professor Andy Taylor and Dr. Rob Linforth and colleagues have already pioneered the use of atmospheric pressure chemical ionisation methods for the detection of flavour molecules using conventional quadrupole mass spectrometers. They are now looking to extend the speed and sensitivity in their research by using TOF-MS, as well as extending their ionisation methods to include proton transfer reaction chemistry (PTR).
An intriguing aspect of their research methodology is to monitor the appearance of flavour molecules with elapsed time on the breath of a person who is sampling a food product. Naturally, the basic experiment is quite short, and as much data as possible needs to be gathered in that time. The parallel detection capabilities of TOF-MS are very attractive from this point of view. It is hoped that new correlations might be observed that were hitherto not possible using a sequential (scanning) mass spectrometer.
Kore has designed a front-end interface for the instrument that will permit the use of existing APCI sources, as well as a Kore-designed PTR ion source. The use of the hydronium ion (H3O+) as an ionising primary beam is known to be effective for the soft ionisation of organic molecules. The principle is quite simple; it is energetically favourable for a hydronium ion to transfer its proton to most organic molecules during a gas phase collision process. By operating the PTR source at a pressure regime where multiple collisions are likely, and by ensuring that the population density of hydronium ions is high compared to the analyte molecules, there is a high conversion efficiency of the analyte molecule of interest to a protonated ion. Furthermore, this proton transfer occurs with little excess energy, with little or no fragmentation of the analyte molecule. So long as the analyte molecules are dilute (<50ppm), there is little chance of analyte molecule A meeting analyte molecule B, and thus complex chemical ionisation reactions between analytes are avoided (unlike in ion mobility spectrometers, or IMS).
The instrument is due for delivery in mid-September.
June 2005: New Metal Cluster TOF-MS for Leicester University
We are pleased to announce that we have received a new order for a research TOF-MS instrument from Leicester University's department of Physics and Astronomy. The mass spectrometer will be used to characterise the masses and distribution of metal clusters produced by a Leicester cluster source. The beam of neutral metal cluster particles will pass through the source region of the TOF-MS where they will be ionised and then pulsed out orthogonally into the mass spectrometer. Kore is supplying the TOF-MS with all control electronics, as well as computer and mass spectral software.
One of the issues for detection of heavy masses in such instruments is the conversion efficiency when these cluster ions reach the detector. For a given energy, the velocity decreases as the mass of an ion increases, and this results in a significant reduction in the conversion efficiency at higher masses (failure to detect the ion). To counteract this effect it is common to used a technique known as "post acceleration", to increase the velocity and thus conversion efficiency of the ions. In this instrument, since the clusters will be ionised at near ground potential, it is necessary to float the detector to high voltage to achieve this post-acceleration. The instrument has the capability of operating with 10kV of post-acceleration on the detector. Work at NPL by Gilmore and Seah (Int. J. Mass Spectrom. 202 (2000) 217) has suggested that metal cluster ions require considerably less post-acceleration to achieve the same conversion efficiency compared to organic bio-molecules (such as those detected in MALDI experiments), and at 10kV of post acceleration the data suggests metal cluster detection efficiency of >75% for masses of 5,000 daltons, and >40% for masses of 10,000 daltons.
The instrument is due for delivery in mid-October of this year.
September 2004: UHV Projection Lens System For UCLA (Genesis Solar Wind Mission)
We are pleased to announce that on August 9th we shipped a UHV Projection Lens System to the University of California in Los Angeles (UCLA). The Kore system represents a small part of a large accelerator SIMS instrument known as "Mega SIMS" that is being built at UCLA. The Kore system will allow the UCLA researchers to image and measure the secondary ion beam before it enters the accelerator section of the instrument. The projection lens system comprises two high voltage lenses (up to 16kV), after which there is a UHV sliding stage that allows the beam to be positioned at either a DMCP/phosphor assembly with an external imaging camera, or at an electron multiplier for pulse counting of the specific masses, or at a Faraday cup for ion currents where pulse counting is no longer applicable. Fast switching between the counting detector and the Faraday cup is made possible by a set of beam deflectors.
The accelerator SIMS will be one of the facilities analysing the captured solar wind samples that return to earth in September 2004 as part of the Genesis project. It is widely accepted that an accurate oxygen isotope composition measurement for the Sun, which represents >99% of all material in the present- day solar system would distinguish between current theories of solar system formation.
Kore is happy to be selected to provide a small but integral part of this powerful instrumentation. We wish the UCLA team every success in their important measurements. For more information on the Genesis Solar Wind Collection Mission, please see their website.
September 2004: Ion Energy Analyser TOF For Birmingham University
We have received an order from the Nanoscale Physics Group of the Department of Physics at Birmingham University to design and build a linear TOF spectrometer and counting chain suitable for energy measurements of ions liberated from surfaces by femto and attosecond laser pulses. The instrument will have an ion extraction lens for collection and injection of the liberated ions into the linear spectrometer. A dual microchannel plate (DMCP) detector and floating pre-amplifier will measure the ion flight times to a resolution of 250ps with a fast time to digital converter (TDC). The time spectrum will be displayed on a host computer operating GRAMS A/I software and Kore extensions. Time resolutions of 250ps will provide energy step resolutions of 0.12eV for m/z 28 or greater, at flight energies of 2keV. In addition to ion spectroscopy, it is anticipated that some electron time of flight spectroscopy will be also possible with the same analyser. To that end, the system will be fitted with a Mu-metal shield and fabricated with suitable materials and techniques to minimise the effects of the earth's magnetic field as well as any local magnetic fields.
September 2004: PTR-MS
We are now underway with a new proton transfer reactor project. In this latest project we will be designing a new PTR source from first principles using high pressure ion modelling developed in-house by Kore Technology. We are aiming for a high analyte ion output from the source, followed by coupling optics that will allow us to transfer these ions with minimal losses into the mass spectrometer. The aim of course is to achieve high sensitivity, and we will be building on the experience from our previous PTR-MS projects.
April 2004: Kore collaborates with IFOS in SNMS instrument development
We are pleased to announce that we have recently received an order from IFOS (Institut Für Oberflächen und Schictanalytik - Surface and Thin Layer Analysis) at the University of Kaiserslautern in Germany. We will be working with them to develop a version of their sputtered neutral mass spectrometer (SNMS) that will perform mass analysis using a time-of-flight mass spectrometer (TOF-MS).
In recent years, surface analysis using ultra low energy (ULE) depth profiling has been critical for characterisation of near-surface semiconductor structures. The commercial instrumentation has been based on the SIMS technique, with primary beam energies as low as 250eV. Although SNMS does not currently offer the possibility of analytical areas much below 1mm, SNMS is highly suited to unpatterned materials where small probe size is not relevant. Indeed, many commercial SIMS analyses are performed on such unpatterned samples. Unlike SIMS, the yields in SNMS are matrix independent, and quantification is more straightforward. Also, because there are no multiple, focussed primary ion columns, the apparatus is less expensive. We are excited about the possibility of adding the advantages of TOF mass spectrometry to the SNMS method - namely parallel detection of all ions as well as improved sensitivity.
This is the second interaction that Kore will have with IFOS; last year IFOS built a TOF-SIMS instrument based on Kore's R-500 TOF-SIMS analyser. If all goes well with the new project, we may be looking at a new generation of high-performance SNMS instruments available at much lower cost compared to ULE SIMS.
April 2004: Frank Nuber, Kore's MS-200 expert, gains PhD
Congratulations to our colleague, Frank Nuber, who has just received his doctoral degree from the University of Hertfordshire. The title of his thesis is "Development and application of a portable volatile organic compound analyser". Frank is our in-house expert on the use of the MS-200 analyser. As anyone knows who has worked for a Ph.D., the effort is large, but Frank's achievement is all the more impressive because he has done the bulk of the work for his thesis while performing a full-time job here at Kore. Congratulations, Frank. Mine's a pint of Abbot!
April 2004: Kore becomes distributor for Applied Physics Technologies
Applied Physics Technologies provides high quality state-of-the-art cathode materials and components. Kore is pleased to have been appointed as a European distributor, and UK agent for OEM sales, of their lanthanum hexaboride (LaB6) and cerium hexaboride (CeB6) cathodes.

If you would like to discuss your customised, analytical requirements with us, please contact Fraser Reich ()
January 2003: Leicester University Orders Chemical Ionisation (CI) TOF System
Kore Technology Ltd is very pleased to announce that we have been commissioned to build a research instrument known as the CI-TOF (Chemical Ionisation Time-Of- Flight) analyser for Leicester University under the direction of Dr. Paul Monks and Dr. Andrew Ellis.
Volatile organic compounds (VOCs) contribute to the generation of photochemical ozone, oxidants, and aerosols in the atmosphere. A vast range of VOCs are emitted into the atmosphere with differing loadings, volatilities, chemical functionalities and reactivities, but at present these compounds are poorly speciated. The team at the University of Leicester are developing a new method for fingerprinting VOCs in air using time-of-flight mass spectrometry, a technique that allows characteristic patterns from the break-up of molecules to be determined.
The University of Leicester team are developing a new form of chemical ionisation source that will allow the preferential ionisation of a wide range of VOCs. This source, coupled to a state-of-the art bespoke Kore TOF-MS, will give near-real time full spectral coverage. The application of time-of-flight mass spectrometry coupled to the Leicester ion source has the potential to offer significant advances in VOC detection with many potential applications.
Dr. Monks said
"The advantages of working with Kore has been significant, in that we have got a system tailored to our specific needs, which will allow us to develop our application more rapidly."
September 2002: Kore Moves To Permanent Home In Ely
On Monday September 9th Kore moved into a brand new building on the Cambridgeshire Business Park in Ely, Cambridgeshire. Kore owns the building, and so this will be our permanent home now.
The building has a downstairs area with mechanical and electronics workshops, a clean room for vacuum component assembly and a large floor space for accommodating our various instrumentation and MS-200 production equipment. The upstairs section houses our offices, a kitchen and dining area, the company meeting room, and our bathroom facilities.
Describing the purchase of a new building and the creation of a permanent home for Kore, the company's Chairman, Dr. Barrie Griffiths, said
"We are very proud of our achievements from a technological and business point of view. Over the last eleven years, we have demonstrated that not only do we have innovative ideas and a strong technical team, but also the staying power to serve our customers for the long- term. Buying specialised instrumentation and knowing that the company will still be there in years to come is significant these days."
September 2002: Kore Goes Nano
Kore is pleased to announce that from September 2002 onwards we are an authorised dealer for NT-MDT, and are thus able to offer an entire range of Scanning Probe Microscopes (SPM), silicon cantilevers and test sample products to our UK customers. New products include Scanning Near-Field Optical Microscopy (SNOM), and a Scanning Confocal Spectroscopy System using Raman spectroscopy.
NT-MDT SPMs operate in a variety of STM modes such as current imaging (constant z) and topographic imaging (constant I), as well as ST spectroscopy modes. AFM modes include a variety of contact AFM modes such as Force Imaging, Lateral Force Imaging, Adhesion Force Imaging among others. Resonant AFM modes include Topography (semi-contact and non-contact AFM), Phase Imaging, and Two Pass techniques such as Magnetic Force Microscopy (MFM) Electrostatic Force Microscopy (EFM) Scanning Capacitance Microscopy (SCM) and Kelvin Probe Microscopy (SKM).
The SPM systems can be configured with a variety of measuring heads, optical viewing systems and vibration isolation systems. The SPMs can be configured to work with small or large samples, and also biological samples. In addition, versions exist to allow measurement in liquid environments, as well as heating of samples in ambient or controlled environments up to 300ºC. A UHV-compatible SPM is also available.
If you are looking for an affordable, flexible standard or customised SPM, Kore would be pleased to discuss your requirements.
July 2002: Kore collaborates with York University on new PTR-TOF
Kore is pleased to announce that we are to design and build the time-of-flight mass spectrometer section for a new instrument known as a PTR-TOF planned by the Department of Chemistry at the University of York, under the leadership of Dr. Lucy Carpenter.
The PTR-TOF will be used to characterise part per trillion levels of trace constituents in continuous gas streams such as air, at data collection rates of about 1 Hz . PTR stands for 'proton transfer reaction', and represents a way of ionising components by use of a technique known as chemical ionisation (CI). This generally produces less fragmentation of organic compounds compared to other methods such as electron impact (EI) or photo-ionisation, and there is often a greater degree of specificity for the reactions. High sensitivity can also be achieved in CI when the primary ions have ample time to react with the compounds of interest. Ensuring that this occurs is one of the key design features of York's PTR reaction cell.
Selecting H3O+ as a primary reactant ion in the PTR cell further enhances the detection of volatile components in a gas stream such as air because H3O+ ions do not react with the bulk components of air. The proton transfer reaction is shown below, and results in the protonation of the compound of interest (R).
H3O+ + R = RH+ + H2O
Once the compound of interest is ionised, the gas stream containing the ions is passed through to the TOF section where a pulsed beam is produced and then mass analysed using the TOF mass spectrometer. TOF has the advantages of higher transmission, parallel detection and a higher mass range compared to quadrupole analysers, and is well-suited to characterisation and operation of the PTR cell.
When asked why Kore had been chosen to provide the mass spectrometry section of the instrument, Dr. Carpenter made the following comment...
"Kore are recognised experts in the field of TOF spectrometry, and we have worked closely to bring our separate expertise together to make what we hope will be an exciting research instrument."
May 2002: Kore exhibiting the MS-200 at ET2002, NEC Birmingham
Kore will be exhibiting at the Environmental Technology (ET2002) exhibition at the NEC in Birmingham during May 21-23rd this year. We will be at stand 1108, where we will be exhibiting our MS-200 portable mass spectrometer. The exhibition is open from 10 a.m. to 5 p.m. and is free to all visitors. As well as exhibitions from more than 150 companies with products in the environmental field, there will be a variety of free seminars throughout the three days, run by groups such as UMIST, the Environment Agency and the Institute of Energy, among others.
If you would like to see the MS-200 portable mass spectrometer in action, this presents an ideal opportunity for you to do so, combining it with a visit to this comprehensive exhibition for people buying or specifying products in environmental, water or waste equipment. For more information about the content of the show seminars and the various other aspects of ET2002, please visit the ET2002 website.
April 2002: Kore renews license as re-seller of NIST mass spectral library
Kore has renewed its agreement with NIST and continues as a licensed re-seller of the widely used and highly respected NIST mass spectral library of electron impact (EI) ionisation spectra. The package includes a powerful software program that provides a variety of search modes for interrogating the library of compounds.
This database is the product of a multiyear, comprehensive evaluation and expansion of the world's most widely used mass spectral reference library.
We recommend this software package as an option with our MS-200 portable mass spectrometer when the instrument is being used frequently for the analysis and identification of unknown compounds. However, the NIST package is a powerful, stand-alone tool for anyone working with EI mass spectrometry. If you would like more information, please click on NIST mass spectral library
January 2002: The 'Cambridge Phenomenon' Moves Northwards, And So Do We!
After spending 10 years on the Cambridge Science Park, Kore Technology is moving so that we can realize the dream of buying our own purpose-built premises. Kore will be moving in the first week of February 2002. Initially we will move into the "e-space North" building in Littleport, just north of Ely, while we await the finishing of our premises on the Cambridgeshire Business Park in Ely itself. We are scheduled to move into these new premises in Ely in the autumn of 2002.
E-space North has been developed by East Cambridgeshire Council in association with St Johns innovation centre to provide flexible, serviced accommodation for high-tech businesses wishing to relocate to the Fens.
The Cambridgeshire area is enjoying unprecedented business growth at the moment, with the building of more science and business parks between Cambridge and Ely in what has been dubbed 'Silicon Fen'. More development is being encouraged in the Ely area due to its easy transport access, reasonable land and property values, and because it disperses commuters away from Cambridge's worsening traffic congestion problems. Ely rail station is one of Eastern England's main rail hubs, and there is a fast train service from Ely to London's King's Cross rail station and also London's Stansted airport. Ely is an attractive and expanding Cathedral City, being the major centre in East Cambridgeshire, and is located just 13 miles north of Cambridge.
Kore will become "greener" too: our new building will be built with modern, energy saving facilities and, since Ely train station is within 5 minutes walking distance of our new site, we can adopt a more "green" transport policy than has been possible on the Cambridge Science Park.
November 2001: Kore "Cryo Preparation System" featured at SIMS 13 Conference
"Under the supervision of well-known SIMS expert Professor John Vickerman of U.M.I.S.T., Ben Cliff and Nick Locker presented their most recent work on the cryo-preparation of biological materials at the recent international conference on secondary ion mass spectrometry (SIMS 13) in Nara, Japan November 11-16 2001.
In a paper entitled " Development of Freeze-Fracture Instrumentation for Routine ToF- SIMS Analysis of Biological Material", Mr. Cliff, a Ph.D. student, presented new imaging SIMS data taken from individual cells fractured through the lipozomes of the lipid bi-layer. Such samples are really model samples. Once the techniques have been perfected in these simpler systems, Mr. Cliff is planning to move on to 'real' biological systems to investigate such phenomena as the localisation of antibiotic synthesis and also the visualisation of bacterial spores.
All his work is being achieved with the MS-2000 Bio-ToF, co-designed by Kore, and details of the cryo preparation system are now detailed on this web site."
October 2001: Languages for Export Award
Kore has recently won a regional Languages for Export Award in recognition of the efforts that Kore employees have made in learning the Japanese language. The awards scheme is run by Trade Partners, the UK Government's amalgam of organisations encouraging export. Fraser Reich and Caroline Pyne accepted the award on behalf of Kore at an awards ceremony in Cambridge.
September 2001: Kore's tenth anniversary
Kore celebrates its 10th year of operations this month. Kore has had steady year on year growth over this decade to become a centre of excellence in time-of-flight mass spectrometry. The products developed during our first decade are unique, including: the world's first portable TOFMS, a table-top TOF-SIMS and a chemical imaging TOF-SIMS designed for Biosciences research. We aim to continue to be "at the heart of innovative analysis" during the next decade.
September 2001: Dr. Fraser Reich joins Kore as Marketing Manager
Kore is pleased to announce the appointment of Dr. Fraser Reich as their new Marketing Manager. He spent the last ten years in the U.S., first as an Applications Scientist with Charles Evans and Associates in Redwood City, California, where he was one of the core team developing their commercially successful time-of-flight SIMS instrumentation for surface analysis. Following the acquisition of CE&A's instrument group by Physical Electronics, he was appointed Senior Scientist with special responsibilities for marketing of their time-of-flight instrumentation and, more recently, their quadrupole-based surface science instrumentation.
When asked about his return to the U.K., and what he hopes to achieve at Kore, he says
"As well as working with a first class team of scientists in the U.S., I have had the privilege of working with an extremely good marketing and sales group. I learned by example that the most successful marketing people in the instrument business are those people who combine their in-depth product knowledge with a desire to see the company's products matched up with clients' analytical needs. That makes for a very powerful, winning combination.
I am genuinely excited by the innovation in on-site analysis represented by the MS-200 portable mass spectrometer, and I am convinced that Kore needs to get the word out more widely about the features and benefits of this compact marvel. I am looking forward to taking up this challenge for this and the other high quality products from Kore."
March 2001: Yuno - Technology Ventures
Kore has announced the formation of YUNO , a technology venture company based in Cambridge. YUNO will identify, acquire, develop and market emerging technologies in the analytical and measurement field. The emphasis is on unique enabling technologies that fuse information technology and natural and physical sciences, in a novel way and most importantly have the ability to transform the current practice in a particular application or market. YUNO, using KORE technical resources, will fund the beta phase of product development by helping to develop a product tailored to a specific application and market.
April 2000: Technology consulting
From time to time Kore provides technical audits, feasibility studies, market analysis and competition analysis in the analytical instrument field. Our particular knowledge of the Japanese market is a useful expertise. A recent market study was completed for the University of Birmingham Nanoscale Physics Laboratory
October 1999: Horiba Partnership
Horiba has increased its shareholding in Kore to about 24% of the total equity making Kore an affiliate of the Horiba Group. Horiba will also continue to fund the development of Kore's innovative mass spectrometer products, which will be marketed under the Horiba-Kore label. Research components and special systems will continue to be marketed under the Kore name. Horiba has also agreed to fund a PhD student in Professor John Vickerman's group at UMIST, England to work on the continuing development of the MS-2000 Biosciences research chemical imaging time-of-flight mass spectrometer.
September1999: Quantar Technology
Kore is pleased to offer our European customers detector products that are complementary to the Burle Electro-optics product line. A new addition is Quantar Technology Inc. Quantar offers a full line family of position-sensitive, single-event-counting imaging detectors and systems for use in scientific and industrial applications.
August 1999: Galileo Scientific Detectors becomes Burle Electro-optics
Kore sells and provides technical support for Galileo Corporation's Scientific Detector products in Europe. Burle Industries Inc. of Lancaster, Pennsylvania USA acquired Galileo Corporation's Scientific Detector and Spectroscopy Products Business this July. Burle Industries is a leading American manufacturer of electron tubes including photomultiplier tubes and silicon target imaging devices for use in diverse fields such as medical research and diagnostic imaging, surveillance, underwater and space exploration. Burle is also a leader in the manufacture of power tubes and cavities used in high energy research, radar, and communications such as FM and VHF TV broadcast transmission. Burle is operating the Galileo business at its present location in Sturbridge, Massachusetts as part of Burle Electro-optics Inc. So now we are selling and supporting the Galileo scientific detector products under the Burle Electro-optics Inc name.
Under the two year joint development contract with Horiba, Kore has developed the MS-200 - a second generation portable mass spectrometer to supercede T-CAT. Three MS-200s are undergoing trials and the product is expected to be released in the New Year under the Kore- Horiba label.

- Change old unsupported racks of electronics for a single, up-to-date enhanced performance unit.
- Take advantage of inexpensive, easy to use, modern software by working under a widely used operating system (Win 3.1x or Windows 95) with standard format files (e.g. images in *.bmp format)
- Have full access to data in open format files.
- Take advantage of the many integrated features available with mainstream third party packages, e.g. easy transfer of data to reports, database facilities, object linking/embedding and much more.
- Already in use on VG Poschenrieder and Kratos Prism instruments
February 1998: Pittcon '98
Joint development of TOF-MS products with Kore The Horiba Corporation of Japan have for some time maintained an association with Kore Technology Ltd taking an interest in our unique compact-TOF-MS technology, which is effective in the measurement of VOCs. In order to reinforce this mutual cooperation, Horiba have recently agreed to conclude a two year joint development contract with Kore for two types of compact and low cost TOF- MS products.
Fire scene investigators from Strathclyde Fire Brigade, Scotland, expressed a need for an effective tool to determine the presence of liquid accelerants early on in suspected cases of fire raising.
Recent results from our portable mass spectrometer MS-200 (Portable Converging Annular Time-of-flight mass spectrometer) demonstrate its ability to measure ambient air contamination in the low p.p.b. region.
