Experience the combined power of two essential libraries for mass spectral analysis 

The Wiley Registry/NIST Mass Spectral Library 2023 is the most comprehensive combined mass spectral library commercially available, with over 3 million spectra (includes EI and 

tandem MS data) making it the clear choice for general unknown compound identification. Broad, up-to-date compound coverage ensures identification across multiple use cases 

and a wide variety of analytes.

Here are just some of the reasons why the 2023 release of the Wiley Registry/NIST library is a critical resource for any lab engaged in MS analysis:

    • Broad range of compounds for targeted and non-targeted analyses—increase both the speed and likelihood of identification with a comprehensive dataset.
    • Expanded coverage of world patents, including USA, China, Japan, and Europe in the 2023 release to ensure your lab remains current.
    • Spectral records contain additional information that’s searchable such as physical properties, structures, and DOIs when available to help narrow your results even further.
    • Data is carefully curated and reviewed by Wiley’s internal and external experts to ensure it meets quality standards for results you can rely on.
    • Spectra are segmented into separate libraries including excess replicate spectra that enable robust searching across varied laboratory settings.
    • Available in the most common instrument manufacturer formats to take the guesswork out of compatibility.
    • Includes the NIST 2023 Software (MS Search, AMDIS, MS Interpreter) to keep your lab up to date with the latest analytical tools.
A foundational tool for any laboratory engaged in GC-MS or MS-MS analysis, the Wiley Registry®/NIST Mass Spectral Library remains a lab standard consistently evolving to meet the ever-growing research demands of today in Wiley’s continued commitment to delivering relevant, quality data resources.
