Abstract : During the last seven years, two agencies of the United States Government, the Environment Protection Agency (EPA) and the National Institutes of Health (NIH), have developed a mass spectrometry data base together with computer software to search this data base. The Mass Spectrometry Data Center (MSDC), supported by the United Kingdom Department of Industry, has collaborated in this project. A major objective of the project has been to provide a means of rapid identification of unknown chemical substances by matching their mass spectra against a comprehensive library of verified spectra. The result of this international cooperative effort has been a machine-readable data base of mass spectra of 25,556 different compounds. This EPA/NIH Mass Spectral Data Base is available in two ways: through lease of a magnetic tape from the National Bureau of Standards (NBS) (1) and through interactive access via an international time-sharing computer network (2). The magnetic tape contains the same data listed herein. They include the spectrum, and indexes listing name, formula, molecular weight, and the CAS Registry Number.
