      Motivation: The compound identification in gas chromatography–mass spectrometry (GC–MS) is achieved by matching the experimental mass spectrum to the mass spectra in a spectral library. It is known that the intensities with higher m/z value in the GC–MS mass spectrum are the most diagnostic. Therefore, to increase the relative significance of peak intensities of higher m/z value, the. Olsen et al. also present mass spectrometry (MS) analysis of m-cresol produced from toluene by toluene-grown cells of PAO1/pRO (Fig. 3A in reference 21). Although MS spectra of o-, m-, and p-cresol are very similar, as one would expect from chemical isomers, the fragmentation pattern of p-cresol is different in its ratio of m/z fragments.

Heller and G.W.A. Milne; and its two supplements This edition is a little hard on the eyes, but contains more spectra. Five algorithms proposed in the literature for library search identification of unknown compounds from their low resolution mass spectra were optimized and tested by matching test spectra against reference spectra in the NIST-EPA-NIH Mass Spectral Database.

The algorithms were probability-based matching (PBM), dot-product, Hertz et al. similarity index, Euclidean distance, and absolute value. The Mass Spectrometry Data Center compiles, evaluates, correlates and measures Standard Reference Data and develops and disseminates associated electronic databases and analysis software for chemical identification and quality control for (a) electron ionization mass spectra and associated retention properties by the technique of gas chromatography/mass spectrometry, (b) reference tandem mass.

Ninety-five percent of the chlori- nated compounds in the library were "found"; and mass spectra of chlorinated com- pounds were assigned scores which averaged 18 times higher than those of non- chlorinated species. By that time, the EPA/NIH Library had grown to ~K compounds from spectra added by NBS (both acquired from third parties and tabulated from the scientific literature).

InNBS changed its name to the National Institute of Standards and Technology, and the library became known as the NIST/EPA/NIH Mass Spectral Library.
