Dr. Matthew S Klee, XO Associates LLC, Northborough, MA

COURSE DESCRIPTION
This course is aimed at providing a working knowledge of how gas chromatography (GC) headspace samplers work, the differences between the various headspace samplers in common use, how method setpoint parameters affect performance, repeatability, and reproducibility.

WHO SHOULD ATTEND
This course is oriented to current headspace-GC users as well as lab supervisors responsible to ensure established methods are properly implemented. Fundamental physical and mechanical processes will be presented in a way that will help users be more comfortable and effective in operating and maintaining their instruments and in transferring legacy methods on newer instrumentation.
