From the Leader in Spectral Data

The essential GC-MS library for confident spectral analyses

Maximize the likelihood of identification with expanded compound coverage in the latest release of this trusted resource

The field-tested and proven Wiley Registry® of Mass Spectral Data continues to empower laboratories worldwide. The 2023 release of this vital MS database provides access to over 873,000 spectra with expanded coverage to expedite your workflow even further. Designed for use across multiple applications, from untargeted GC-MS screening to accurate mass workflows with MS-TOF instruments, this comprehensive collection helps to ensure confidence in your lab’s spectral search results, even in the most demanding applications.

  • 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.

A foundational tool for any laboratory engaged in GC-MS analysis, this 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.

Available in the most common instrumentation manufacturer formats, this spectral library is a necessity for any laboratory engaged in GC-MS analysis.
Now also available as a KnowItAll subscription for continued access to new data between major releases.
