NIST Expands Its Library of ‘Chemical Fingerprints’ to Identify Unknown Substances
The National Institute of Standards and Technology (NIST) has updated its comprehensive library of chemical fingerprints, known as mass spectra, with tens of thousands of new compounds. This expanded library, NIST26, now contains hundreds of thousands of unique chemical signatures generated using mass spectrometry. Researchers and manufacturers utilize this resource to identify unknown substances across various fields, including medicine, environmental science, and space exploration. AI
