GC Temperature Programming - 10 Things You Absolutely Need to Know

Thursday 31st July 2014,
8:00am PDT / 11:00am EDT / 16:00 BST / 17:00 CEST

Find out what has made it onto our top ten list of things you absolutely need to know about GC temperature programming. Presented by Tony Taylor (Technical Director, Crawford Scientific).

  • The effect of temperature on analyte migration
  • What are the differences between isothermal and gradient GC?
  • What can a scouting gradient tell us?
  • Predict the optimum isothermal conditions
  • How to optimize isothermal conditions
  • What initial temperature should be used in a temperature gradient?
  • Should an initial hold time be used in a temperature gradient?
  • The optimum ramp rate and mid-ramp holds
  • When and at what temperature should a GC temperature program end?
  • How fast can a GC separation be?

Key Learning Objectives:

  • Understand the fundamental parameters of GC temperature programming

Developing Better GC Methods - A Blueprint

In order to obtain sensitive, robust, and reproducible gas chromatography (GC) methods, each stage of the chromatographic process needs to be optimized.   It is also important to record and report as much detail pertaining to each parameter in order for methods to be reproduced between operators and between laboratories.  Using a generic GC method outline, and a generic sample (Table 1), each stage of the GC chromatographic process will be examined resulting in a 'blue print method' that can be used to ensure all parameters are considered, optimized and included in the final method specification.
