GC Headspace

Half Day Course

This half day course provides a 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, instrumentationm troubleshooting and optimisation/development of conditions.

  • We limit numbers to 10 per course so that each delegate gets the opportunity to ask questions and fully participate in tutorial exercises
  • When delivered on-site we can design the course material to suit your specific training needs
  • Customisable written assessments are available if required


Who is this course for

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

Previous knowledge

Good knowledge of chromatography and associated data.
