Wiley MS Library – Webinar Series of Effective Use of Mass Spectral Databases

Wiley will be presenting a free 5-Part webinar series on how to conduct spectra and structure search through the NIST MS Search Program. The Series begins on August 25th, at 10:00 am EDT.

These webinars will be presented by James Little, formerly with Eastman Kodak as a Research Fellow for many years, and currently serves as a consultant for the NIST on the MS search development.

Wiley's mass spectral libraries are a powerful tool for the identification of organic compounds in complex mixtures by mass spectrometry. This series of seminars will demonstrate the use of the NIST (National Institute of Standards and Technology) software suite for accessing Wiley, NIST, and even user-generated libraries. The software includes MS Search, MS Interpreter, and AMDIS plus ChemSketch for structural drawing. The series should be useful to a wide variety of research and developments scientists involved in medical, environmental, industrial, forensic, and biological disciplines.

Initial sessions will primarily discuss electron ionization gas chromatography/mass spectrometry (EI GC/MS) data. However, many of the principles are applicable to tandem spectra obtained by liquid chromatography/mass spectrometry (LC/MS) which will be discussed in the latter part of the series.

Part 1 Spectral Searches with NIST MS Search Aug. 25, 10:00 EDT

Part 2 – Structure Searches with NIST MS Search – Sept. 1, 10:00 EDT

Part 3 – AMDIS for Processing EI Mass Spectral Data Files – Sept. 8, 10:00 EDT

Part 4 – Advanced NIST Hybrid Search of EI and Tandem Libraries – Sept. 15, 10:00 EDT

Part 5 – Creating and Sharing User EI and Tandem Libraries – Sept. 22, 10:00 EDT

The Importance of CAS Numbers When Requesting Standards

Going through a long list of compounds for an analytical standard and adding a CAS number for every compound on the list is something nobody wishes to do. Unfortunately, it's become crucial for accurate processing of ever lengthening analyte lists, especially for international methods. Many drugs and pesticides have local variations on name or spelling while CAS numbers are constant throughout the world. CAS numbers are now the primary identifier for analytes in most, if not all, ISO 17034 Certified Reference Materials.

To let us help you find the best solutions for extensive analyte lists please:

  • Include CAS numbers whenever you have them.
  • Include a technical contact to clarify any oddities in a list when submitting a quote request.
  • Let us know if you need us to add the CAS numbers for you. Otherwise we'll need to check if you have or can get them.
  • If you need us to add CAS numbers, understand it will take us time to do so, and that you'll need to review and approve the CAS numbers and associated chemical names before you order.

The following 2 sites are places where CAS numbers can be found:
