Introduction to GC-MS

Headspace Analysis Guide for GC-MS
Contributor: Paul Tschida, 2013
http://www.restek.com/pdfs/59895B.pdf
Content: A technical guide containing information about headspace analysis via GC-MS, including basic principles, troubleshooting, and applications.
Reliability and Usefulness: Considering that it is a technical guide, it seems very reliable. It would be very helpful in providing an easy way to analyze the fragrances in a substance.

A Technical Guide for Static Headspace Analysis Using GC
Contributor: Madison Wilson, 2013
http://www.restek.com/pdfs/59895B.pdf
Content: Describes the basic principles of headspace analysis, information on the instrumentation and sampling, headspace applications, and a few other things.
Reliability and Usefulness: Seems reliable. Was helpful in understanding how headspace analysis works, and how sample is injected.

Spectral Database for Organic Compounds
Contributed by: Koty Emery, 2015
Source: http://sdbs.db.aist.go.jp/sdbs/cgi-bin/cre_index.cgi
Content- This is a great database that contains MS, Carbon NMR, HNMR, IR, Raman, and ESR Spectra for many organic compounds.
Reliability & Usefulness – This resource would be helpful for obtaining reference spectra during the flavoring, volatile compounds, and CYOA portions of the course.

Mass Spectrometry: How it works and how to interpret it
Contributed by: Kyle Milke, 2016
Source: http://www2.chemistry.msu.edu/faculty/reusch/virttxtjml/spectrpy/massspec/masspec1.htm
Content- This is a really good website on mass spectrometry.  This website describes how the instrument works and also how to read the fragmentation patterns.  It even has a small interactive action where you can see how the molecules spit based on their M/Z.
Reliability & Usefulness – This source is reliable because it is made by someone at Michigan State University.  It is also helpful in understanding the fragmentation patterns produced by molecules.

  1. This is a great website for deciding what parameters to use when running a sample through the HPLC. You can select a group on the right side of the screen (ie Food and Beverage) and then further refine your search to try and find your specific product, or at least something similar.
