Understanding GC Methods

The first in a series of webcasts aimed to develop the skills and understanding of GC users. In this session we will take 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 include:

• Working principles of the split/splitless injector
• Optimization of sample injection variables
• Inlet liner selection
• Column installation
• Setting initial oven temperature and hold time
