Introduction

GC-MS is an important technique for the identification of volatile components. In this course, you will learn to interpret GC-MS mass spectra systematically.

Target group

You work as a (senior) analyst or employee in a bachelor level laboratory and work with GC-MS, for example in environmental laboratories, the food industry, the chemical industry or pharmacy. You want to gain insight into the fragmentation of ions in GC-MS and learn how to obtain information about the molecular structure from mass spectra. You have a good basic knowledge of organic chemistry. Since this is indispensable, it forms a major requirement.

End result

At the end of this course, you are able interpret simple to slightly complex EI mass spectra. You can assign fragment ions of molecules. This helps you to solve confirmation and identification problems in GC-MS analyzes. You are able to critically evaluate the results of library search procedures.

Program

Day 1 (December 17. 2018):

  • Introduction to electron ionization mass spectrometry
  • Molecule ions, (accurate) mass, nitrogen rule, RDBE

  • General interpretation procedure, ion series.

Day 3 (December 19, 2018):

  • Use of mass spectral libraries
  • Important fragmentation mechanisms: Secondary fragmentation reactions
  • Mass spectra of component classes
