Packaging SIMS samples – SurfaceSeer Sample running

We do not maintain a demo suite at Kore, but we can arrange to run demo samples for on some of our customers’ SurfaceSeer instruments. 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. A short report will be issued by Kore, who have years of experience in interpreting TOF-SIMS data.

 

If you are interested to have a sample run, please contact Fraser Reich first (dfr@kore.co.uk or via the enquiry form) who will discuss the matter with you.

Sample preparation

TOF-SIMS is very surface sensitive – poorly prepared samples produce poor results! If you are interested to supply a sample, please follow these simple guidelines:

 

  • Never touch a sample with your bare hands, always use fresh laboratory rubber gloves (nitrile) and clean tweezers.
  • Cut sheet material with clean scissors and mark the side to be analysed with a permanent marker pen: put a cross in the corner.
  • Never place samples inside plastic bags! The internal surfaces of almost all plastic bags are covered in siloxane release agent. This is very mobile and will contaminate your sample.
  • Use fresh aluminium foil (standard kitchen foil is very clean) and place the sample onto the foil and fold the foil to make an envelope around the sample.
  • Remember that the SurfaceSeer sample holder is currently suited to sheet material.
  • Please provide what useful information you can about the sample, particularly if you want to send us a ‘good’ sample and a ‘bad’ sample for comparison.

 

Using a sheet of aluminium foil creates a very clean sample preparation area. Always use fresh gloves, clean tweezers and clean scissors.

 

Now the sample is prepared. You do not need to cut the material into suitable-sized samples – you can supply a larger sheet, and we will prepare the sample. Photographed against a paper sheet for clarity – but always use a fresh sheet of aluminium foil as your worktop.

 

Place the sample (ringed in red) onto clean foil and fold the foil to make a clean envelope.
