The CHROMacademy Essential Guide Webcast:
Understanding GC Sample Introduction

Thursday 12th December 2019,
11:00am EST/ 8:00am PST/ 4:00pm GMT/ 5:00pm CET


 

 

 

Sample injection is an essential step in any GC (or GC-MS) method. It must be optimized to ensure that the efficiency which is gained through the use of GC is maintained. Each sample introduction type has specific requirements and parameters which must be correctly set to provide optimum chromatography. This webcast will examine the sample introduction parameters associated with the most common type of inlet, split/splitless.

Key Learning Objectives

An in-depth look at principles of GC sample introduction and the associated variables which need to be defined in GC methods. We describe the principles of sample injection and describe in detail how method variables are set and optimized using real life good and bad method examples.

Topics Covered

  • The working principles of the split/splitless injector
  • The major and minor variables which control sample injection
  • Optimization of injection variables
  • Inlet liners and problems caused by incorrect liner selection
