Mass Spectral Library Searching Stephen E. Stein NIST Mass Spectrometry Data Center, Gaithersburg, Maryland, USA A library-search procedure that identifies structural features of an unknown compound from its electron-ionization mass spectrum is described. Like other methods, this procedure first retrieves library compounds whose spectra are most similar to the spectrum of an unknown compound. Das NIST beauftragte in den 1970er Jahren u. a. die Boulder-Gruppe mit der Messung der Lichtgeschwindigkeit und der Neudefinition des Meters.

Coupling of mass spectra with retention indices: This is a topic which was unfortunately neglected in the past, but will be very important in the future for the identification of organic substances with GC-MS. Identification of substances only via mass spectra or retention. Spectra from the NIST/EPA/NIH Mass Spectral Library. Reprinted with permission from NIST. Since molecular ions fragment in predictable ways, the presence of certain fragmentation peaks can suggest that a particular peak is the molecular ion. The observed fragments must be able to be attributed to logical losses. The existence of a M - 15 peak from the loss of CH 3, a M - 18 peak from the loss. Performance of several library search algorithms (against EI mass spectral databases) implemented in commercial software products ( acd/specdb, chemstation, gc/ms solution and ms search) was estimated. Test set contained 1000 mass spectra, which were randomly selected from NIST'08 (RepLib) mass spec
