Wiley Seminar - Part III: AMDIS (NIST) for Processing EI Mass Spectral Data Files

I presented a 5-part Wiley Webinar Series in August-September, 2020 on EI library searches. 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 Part III will cover:

Detailed Handouts including tables of content are available in the LabRulezGCMS library.

• Help files and manuals
• Common Windows commands/functions
• AMDIS essentials
• Opening files
• Deconvoluting spectra and obtaining manual spectrum using LMB
• Evaluating results
• Externalsearching of commercial/user libraries with NIST MS
• Uncertain peaks
• Plotting selected ion chromatograms in normal and log scale
• Manually obtaining background subtracted spectra
• Internalsearching (no structures) of commercial/user databases
• Internalsearching (no structures) of target libraries
• Optimizing peak detection
• Comparing two chromatograms for differences
• Retention indices
• Problemno chromatogram/spectrum window
• Webinar References
• Acknowledgements

Future parts will focus on:

• Part IV: Advanced NIST Hybrid Searchof EI and MS/MS Spectra

• Part V: Creating and Sharing User EI and MS/MS Libraries

The past sections have focused on:

• Part I: Spectral Searches with NIST MS Search

• Part II: Structure Searches with NIST MS Search and Using MS Interpreter
