Confident compound identification with the most comprehensive GC-MS library

The field-tested Wiley Registry of Mass Spectral Data,11th edition is the largest mass spectral library commercially available, providing over double the compound coverage of our competitors. Applications include untargeted GC-MS screening and accurate mass workflows with MS-TOF instruments.

Experience improved spectral search performance with the 11th edition. The latest version was extensively validated to sequester and remove suspect spectra from the main library. Replicate spectra (beyond 4 replicates) were moved into a separate replicate library.

The Wiley Registry of Mass Spectral Data, 11th edition provides researchers the most assurance that their untargeted spectral search is the broadest available. Expansion on the new edition brings an additional 56,500 spectra into the library.
