Overview

Confident compound identification with the most comprehensive GC-MS library

The field-tested Wiley Registry® of Mass Spectral Data, 12th 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 12th Edition. The latest version was extensively validated to sequester and remove suspect spectra from the main library. The new edition also introduces the inclusion of chemical classifications, calculated Kovats retention indices, and splash IDs.

The Wiley Registry of Mass Spectral Data, 12th Edition provides researchers the most assurance that their untargeted spectral search is the broadest available.
