I presented a 5-part Wiley Webinar Series in August-September, 2020.  The series demonstrates the effective use of NIST software such as MS Search, MS Interpreter, and AMDIS with the Wiley, NIST, and user-created libraries.  The following links are for either my personal YouTube or Wiley recordings:

Detailed Handouts including tables of content are shown below:

Part I: Spectral Searches with NIST MS Search-9-27-20
Part II: Structure Searches with MS Search and Using MS Interpreter
Part III:  AMDIS (NIST) for Processing EI Mass Spectral Data Files 9-22-20

Part IV: Advanced NIST Hybrid Search of EI and MS/MS Spectra-9-27-20
Part V: Creating and Sharing User EI and MS/MS Libraries

Other Webinar Resources:

Wiley, NIST, and user-created mass spectral libraries are very powerful tools for the identification of organic compounds in complex mixtures by gas chromatography-mass spectrometry (GC-MS).  This series of seminars will demonstrate the use of the NIST (National Institute of Standards and Technology) software suite for searching these EI 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 developmental scientists involved in medical, environmental, industrial, forensic, and biological disciplines.

Hybrid Search Resources from Others:

Gary Mallard from NIST a “real-world” example of a fentanyl-related compound from his work.

Arun Moorthy and Gary Mallard also presented an excellent workshop showing applications of the hybrid search in forensic applications.  The PDF file used in the seminar are shown below.  One will have to register on the website to see the video.
