NIST Adds New ‘Fingerprints’ to Chemical Identification Database

The National Institute of Standards and Technology (NIST) has updated its database of chemical fingerprints, called mass spectra, that are used to identify unknown chemical compounds. The NIST Mass Spectral Library and its new version, called NIST20, is used in health care, drug discovery, foods and fragrances, oil and natural gas, environmental protection, forensic science and almost every other industry that manufactures or measures physical stuff.
