NIST 14 Components
NIST 14 is not just a mass spectral library. It contains these components:
?Electron ionization (EI) mass spectral library - 276,259 carefully evaluated spectra of 242,477 unique compounds, with identifications, nearly all with chemical structures. You may search names of NIST compounds online.
?MS/MS library - 234,284 spectra: 51,216 ion trap spectra for 42,126 different ions of 8,171 compounds, and 183,068 collision cell spectra (qtof and tandem quad) spectra for 14,835 different ions of 7,692 compounds. (Also available separately as the NIST MS/MS Database.)
?Gas Chromatography (
gc) data library - 385,872 retention index values (Kovats/Lee) for 82,337 compounds (50,461 in the EI library), covering both polar and non-polar columns. Includes retention indices with
gc column conditions and literature citations. (Also available separately as the NIST
gc Database.)
