GC Headspace

Live Online

Instructor-led Training

Learn all you need to know about this elegant yet complex sample preparation/introduction of GC samples.

This course provides comprehensive coverage of the most common approaches associated with static headspace methods used in GC.

We look at the foundation principles of the technique, then move to the practical aspects of operation, instrumentation troubleshooting, and optimisation/development of conditions.

Headspace sampling provides a sensitive, robust, easily automated, and quantitative method of analysing volatile substances from complex matrices. All of these positives, however, rely on well-developed headspace parameters and on operators paying attention to some key aspects of preparing and analysing samples.

Our comprehensive static headspace training course covers all aspects of routine analysis, method development, and solutions to some of the common challenges with the technique.

This course is relevant to anyone using static headspace sampling for GC analysis. It is applicable to most instrument designs.
