NIST Standard Reference Database 1A

NIST/EPA/NIH Mass Spectral Library with Search Program (Data Version: NIST 11, Software Version 2.0g)

This database is the product of a multiyear, comprehensive evaluation and expansion of the world's most widely used mass spectral reference library.

(available ONLY from distributors)

What's New in NIST MS Search program v2.0g distributed with NIST 11

Contents of the NIST/EPA/NIH NIST 11 Mass Spectral Library
Library Name Library Description Library Contents
mainlib Main EI MS library 212,961 spectra
replib Replicate spectra 30,932 spectra
nist_msms and nist_msms2 MS/MS Library 95,409 Spectra of 12,568 ions
nist_ri Retention Index Library 346,757 Kovats RI values for 70,835 compounds
Evaluation and Quality Control
  • Each spectrum critically examined by experienced mass spectrometrists.
  • Each chemical structure examined for correctness and consistency, using both human and computer methods.
  • Spectra of all stereoisomers intercompared.
  • Chemical names examined by experts and IUPAC names provided.
  • Thousands of replacements of spectra with higher quality spectra.
  • Verified CAS registry numbers.

This library is available with version 2.0g of the full-featured NIST MS Search Program for Windows, which also includes integrated tools for:

  • GC/MS deconvolution (AMDIS version 2.70)
  • Interpretation of mass spectra (MS Interpreter version 2.0, a thermodynamics-based interpreter of fragmentation)

Main new features of the NIST MS Search Program version 2.0g are: 

  • Search for exact precursor mass in mass spectral libraries.
  • Search for exact fragment ion mass in NIST 11 EI and MS/MS libraries.
  • Import spectra from instrument data system using standard formats including mzXML, mzData, mgf, msp, dta, pkl, JCAMP, etc.
  • Full compatibility with most recent NIST Peptide MS/MS Libraries.
  • Provides a variety of new methods for identifying target compounds or compound classes – even in the presence of noise.
  • Handles up to 127 MS libraries instead of 16, the limit in previous versions.

System Requirements: PC with Microsoft® Windows NT® 4.0, Windows® 2000, Windows® XP, Windows Vista®,or Windows® 7; hard disk with 1GB of available space required.

This includes MS library, Search Program v2.0g, MS Interpreter v2.0, and AMDIS v2.70.

An 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.
