Mass Spectral Libraries (NIST 17 and Wiley Libraries)

Home

We have mass spectral libraries!

  • Identify unknown compounds from EI (GC/MS) and MS/MS spectra by library searching our mass spectral databases.
  • Hundreds of thousands of spectra. EI MS spectra, MS/MS spectra, GC data & retention indices, and/or chemical names/structures
  • World's most widely used and trusted mass spectral reference libraries.
  • Search software included (used by all libraries).
  • Supports most MS software systems (Agilent ChemStation/MassHunter, Thermo Xcalibur, Shimadzu GCMS Solutions, Waters MassLynx, Thermo Xcalibur, PE TurboMass, etc.).
  • We have many libraries:
    • NIST 17 is our recommended base library, large, general purpose, strongly evaluated, and purchased by most customers. NEW: NIST 2017 Release!
    • The Wiley Registry is the the world's largest EI MS library, general in purpose, and optionally combined with NIST MS.
    • Other Wiley specialty libraries focus on specific classes of compounds like drugs, pesticides, flavors and fragrances.
  • Call or e-mail us to discuss your library needs.

  • Wiley Lipids Mass Spectral DatabaseWiley Lipids Mass Spectral Database
    Description by Luigi Mondello, July 2016 Lipids are one of the major constituents of food and they have an essential role in human diet, metabolism, physiological and pathological processes. Many lipids compounds present very similar mass spectra, therefore mass spectra supported by chromatographic is fundamental for correct compound identification in the research field. The Lipids Mass Spectral Database gives significant support for peak assignment in complex mixtures making it a valuable tool...
  • Wiley Pesticides Mass Spectral Library with LRI, 2nd EditionWiley Pesticides Mass Spectral Library with LRI, 2nd Edition
    Description (July 2016) by Prof Luigi Mondello Pesticides and agrochemicals are widely used in the production of large-scale agriculture. Their determination is essential for consumer’s health protection. Mass spectrometry is the most important technology for pesticide analysis and the Pesticides Library provides significant support for peak assignment in complex mixtures. The Mass Spectra of Pesticides with Retention Indices, 2nd Edition, contains 1,300 pesticide molecules classified in 20 d...
  • Wiley Designer DrugsWiley Designer Drugs
