NIST / EPA / NIH Mass Spectral Library 2020
Technique: GC-MS, LC-MS

( product details)

The NIST/EPA/NIH Mass Spectral Library 2020, the successor to the NIST 2017, 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 20 contains over a million mass spectra including 350,000 EI spectra for 306,000 compounds and 1,320,000 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.

The collection is comprised of the following three libraries:

  • Electron Ionization (EI) mass spectral library
  • 4 MS/MS libraries
  • GC Retention Index library
