New release increases speed and likelihood of MS identification with expanded coverage

Sept 29, 2023 — Wiley, a knowledge company and global leader in research, publishing and knowledge solutions, today announced the release of Wiley Registry/NIST Mass Spectral Library 2023. Now with access to over 3 million spectra (includes classical EI and tandem MS libraries), this resource combines the power of two essential libraries for mass spectral analysis with expanded, up-to-date compound coverage to ensure identification across multiple use cases and a wide variety of analytes.

“This database combines two of the best resources to ensure the most comprehensive spectral comparisons, making it the clear choice to aid in classical EI and tandem MS identification,” said Graeme Whitley, Director, New Business Development at Wiley. “By using this comprehensive collection, scientists can increase the speed of analysis and ultimately improve the overall likelihood of correct identification.”

Notable updates in the 2023 release include:

• Addition of over 74,000 unique compounds and over 91,900 spectra

Wiley Registry of Mass Spectral Data:

• Expanded coverage of world patents and peer reviewed literature, including DOIs of source articles.
• The MS/MS Library has added 60% more compounds than the 2020 release, now covering over 51,000 compounds and over 399,000 precursor ions.

NIST/EPA/NIH:

• AI-RI values have been added for all EI data.
• The MS/MS Library has added 60% more compounds than the 2020 release, now covering over 51,000 compounds and over 399,000 precursor ions.

Available in the most common instrumentation manufacturer formats, this trusted MS database is a necessity for any laboratory engaged in classical EI and tandem MS identification.
