NIST/EPA/NIH Mass Spectral Library with Search Program


(Data Version: NIST 14, Software Version 2.2g)

Kore is a licensed re-seller of the widely used and highly respected NIST mass spectral library of electron impact (EI) ionisation spectra. This database is the product of a multiyear, comprehensive evaluation and expansion of the world's most widely used mass spectral reference library. The package includes a powerful software program that provides a variety of search modes for interrogating the library of compounds.

System Requirements

The total installed size is around 1.5Gb. The MS Search program will run on the following Microsoft® operating systems:

Windows® NT 4.0, 2000, XP, Vista or Windows® 7, 8, 8.1

Note: AMDIS, MS Interpreter, and Lib2NIST are not compatible with Windows NT 4.0

This includes MS libraries with Kovats retention index and MS/MS data, Search Program v2.2g, MS Interpreter and AMDIS V2.72.

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. The latest version has been expanded, both in terms of data in the library and also the number of features in the software package accompanying the database.

Evaluation and Quality Control

MS search software

This library is available with Version 2.2g of the full-featured NIST MS Search Program for Windows, which also includes integrated tools for:

Main new features of the NIST MS Search Program version 2.2g are:

Automated MS Deconvolution and Identification System (AMDIS)

This program extracts the spectrum of each component in a mixture analyzed by GC/MS and identifies target compounds. With the support of the Defense Special Weapons Agency (DOD), it was developed at the National Institute of Standards and Technology (NIST) for the critical task of verifying a major international treaty, the Chemical Weapons Convention. After two years of development and extensive testing it has been made available to the general analytical chemistry community.
