WILEY

Introducing the Wiley Registry of Mass Spectral Data, 2023 edition:

• World’s largest library of electron ionization (EI) mass spectra — 1,180,800 spectra for 950,200 unique compounds. It enables you to identify global unknown compounds from EI mass spectra, with the highest likelihood given its unparalleled size and breadth.
• Most spectra are accompanied by searchable chemical structure, trivial name, molecular formula, molecular weight, nominal mass and base peak.
• Applications include untargeted GC/MS screening of EI spectra, accurate mass workflows with MS-TOF spectra, and identification with other search constraints.
• Developed over 40 years by Wiley and Dr Fred McLafferty. Spectra are sourced from leading laboratories throughout the world.
• Uses the same search software as the NIST 23 spectral library and compatible with most MS data systems.

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™ of Mass Spectral Data is one of the most trusted and comprehensive mass spectral libraries in the world, and the gold standard for detection, identification, and quantification in:-

• Pathology
• Forensics/Toxicology
• Environmental Science
• Research and Development
• Quality Assurance
• Homeland Security/Law Enforcement
• Commercial Deformulation
• Food safety and Quality
• Anywhere an unknown compound must be identified, or a known compound must be confirmed.
