Outline of the Workshop

Fundamentals of Gas Chromatography, Mass Spectrometry
and Gas Chromatography-Mass Spectrometry

The objective of this GCMS course, hosted by ChromSA and SAAMS, is to teach analysts and students in practice how to use the systems correctly, how to develop methods successfully, and how to understand and interpret results. This will be achieved through a better understanding of how the instruments work, their strengths and limitations, and the basic fundamentals of the techniques. It is aimed at relatively inexperienced users to develop their skills and understanding, and at more experienced users who want a better knowledge of the instruments they use. This will be handled in depth in a simple and easy to understand set of presentations.

This workshop is an excellent opportunity for everyone working in the field of gas chromatography and mass spectrometry to strengthen their knowledge in this field by learning from an expert, Dr Peter Gorst-Allman.

The Course will examine in detail the following:


Gas Chromatography

  1. Fundamentals of GC (what it does and how it does it).
  2. The inlet (types of inlets and liners, selection of the correct liner, maintenance, and troubleshooting).
  3. The separation (carrier gases and their characteristics, columns and column selection, column analyte interaction, optimal flow, optimal heating rate, troubleshooting).
  4. The detector (types of detectors, their capabilities and where to use them).
  5. How to recognize separation problems and adjust parameters to correct these.

Mass Spectrometry

  1. The mass spectrometer as detector, how it works and the information it provides.
  2. Types of mass spectrometer (quadrupoles, sector systems, time of flight, ion trap: how they work, their capabilities and limitations, full scan vs SIM, MS/MS).
  3. Ionisation methods (how they work, their capabilities and limitations).
  4. Compound identification by MS (capabilities and limitations).
  5. Quantitation by MS.
  6. Maintenance and troubleshooting.


  1. What it gives you and where to use it (GC-MS vs LC-MS).
  2. What to expect from the software.
  3. Interpretation of results.
  4. Maintenance and trouble shooting.

Workshop presenter


Dr Peter Gorst-Allman

Peter Gorst-Allman received a Ph D from the University of South Africa in 1978, and has been involved in chemical research for over 45 years. He spent 15 years at the CSIR, both at the National Chemical Research Laboratory (NCRL) and at the Division of Processing and Chemical Manufacturing Technology (DPCMT) where he was in charge of the GC-MS Group. He headed the GC-MS/NMR Group at AECI for 7 years, and subsequently worked for LECO Africa from 2000 as the Director of Separation Science Applications, for Africa and Asia Pacific.

He has worked in the United States in a Postdoctoral position at Purdue University, and as an Alexander von Humboldt Research Fellow with Prof G. Spiteller at the University of Bayreuth, Federal Republic of Germany. He is the author or joint author of over 60 scientific papers and reviews in International Journals, and numerous Technical Reports and Application and Performance Notes for AECI, LECO Corporation and Leco Africa. He has also contributed chapters to several books on mycotoxins. He has presented at Conferences in Africa, the Americas, Asia, Europe, and Australia as a plenary or invited lecturer.

He is an expert in GC-MS and has worked extensively in this field for over 35 years. His interests are (i) mass spectrometry instrumentation, performance and applications, (ii) gas chromatography instrumentation, performance and applications, (iii) industrial and environmental problem solving and the analysis of organic molecules.
