Operating and Understanding GC

1 Day

This 1 day course introduces the GC system taking you from system set-up to shutdown and covering each component in turn.

The fundamental concepts of GC are explained alongside this to build understanding and confidence in running GC analysis.

Basics of the chromatographic process, inlet systems, column and detector selection are important topics covered to give the participant a thorough grounding in the technique. Instrument hardware is also covered with basic troubleshooting and maintenance tips as well as an introduction to data processing.
