  What does the perfect GC method look like?

  Whilst a perfect method doesn’t exist – important instrument settings and chemistry choices must be considered in order to approach perfection.

  This webcast highlights all of the decisions required to build a rugged and sensitive GC method.

  All sample, sample inlet, column, temperature programming and detector settings are considered in this highly informative and practically relevant webcast.



  Identify key parameters which affect sensitivity and robustness in GC methods.

  Examine key sample and inlet conditions which affect peak shape and quantitative accuracy.

  Highlight key choices with stationary phase selection and column geometry.

  How to build robust and effective temperature programs.

  Optimizing detector response for a range of common GC detectors.

  Building in quantitative robustness to GC methods.

  Highlight the key variable for consideration when developing or optimizing GC methods and using these to build a GC method blueprint.

  Highlight the minor as well as the major instrument variables which affect GC method quality.



  Anyone working with gas chromatography who would like to better understand the methods they use.

  Anyone wishing to improve GC method robustness and sensitivity.

  Anyone involved in developing or transferring GC methods.

Abstract: In gas chromatography, 80% of the trouble is caused by the injection system. Also here we have seen that by degradation of sample components, O-rings, back flash and septa, extra peaks can be generated. Besides this, the conditions used for injecting the sample can also produce serious extra peaks.
