GC Headspace
GC Headspace
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
