NIST/EPA/NIH Mass Spectral Library 2023

NIST/EPA/NIH Mass Spectral Library 2023

The NIST/EPA/NIH Mass Spectral Library 2023, the successor to the NIST 2020, is a fully evaluated collection of electron ionization (EI) and MS/MS mass spectra, with chemical and GC data, plus search software to identify your own unknown spectra. NIST 23 contains over a million mass spectra including 394,000 EI spectra for 341,600 compounds and over 2,300,000 tandem MS/MS spectra. It is a product of a more than three-decade, comprehensive evaluation and expansion of the world’s most widely used mass spectral reference library by a team of experienced mass spectrometrists at the National Institute of Standards and Technology (NIST) in which each spectrum was examined for correctness.

What’s Included:

  • Electron Ionization (EI) mass spectral library
  • 4 MS/MS libraries
  • GC Retention Index (RI) library
  • NIST 2023 Software: MS Search, AMDIS, MS Interpreter

What’s New in this Release?
In the latest release:

  • The EI Library has added over 40,000 unique compounds with more than 43,000 spectra, in addition to AI-RI values for all EI data
    The MS/MS Library has added 60% more compounds than the 2020 release, now covering over 51,000 compounds and over 399,000 precursor ions
    The GC RI Library added over 40,000 compounds
