Wiley Registry of Mass Spectral Data, 11th Edition


ISBN: 978-1-119-17101-0 March 2016


The Wiley Registry of Mass Spectral Data, now in its 11th edition, is the most comprehensive mass spectral library available. Applications include untargeted GCMS screening and accurate mass workflows with MS-TOF spectra. Included in the 11th edition are:

  • Over 775,500 mass spectra
  • Over 741,000 searchable chemical structures
  • Over 599,700 unique compounds

Improvements to The Wiley Registry include removal and sequestration of suspect spectra from the main library and partition of excess replicate spectra (beyond 4 replicates) into a separate replicate library. The result is a main library that has increased overall breadth and improved spectral search performance.

Identification of unknowns begins with untargeted analysis. The Wiley Registry provides researchers with the most assurance that their untargeted spectral search is the broadest available. The Wiley Registry 11th edition has 56,500 and 113,500 more spectra than the 10th and 9th editions, respectively. It contains 264,968 more spectra and 229,068 more compounds than the NIST 14.
