Wiley Registry 12th Edition / NIST 2020 Mass Spectral Library

Wiley Registry 12th Edition / NIST 2020 Mass Spectral Library


The broadest combined library available with over 2 million EI and LC-MSn mass spectra

The combined Wiley Registry 12th Edition/NIST 2020 Mass Spectral Library is the most comprehensive mass spectral library available, making it an essential tool for general unknown compound identification. Included in the combination package are:

- Electron Ionization (EI) mass spectral library
- 4 MS/MS libraries
- GC Retention Index library

Experience improved spectral search performance with the Wiley Registry 12th Edition/NIST 2020 Library. Replicate spectra and over 3 million chemical names and synonyms provide a higher rate of correct identification and ensure that this library can aid in classical EI, exact mass, and other methods of identification.
