Static Headspace-Gas Chromatography Theory and Practice Bruno Kolb * Leslie S. Ettre Static (equilibrium) headspace-gas chromatography (static HS-GC) offers a reliable, simple, and accurate way to quantitate volatile compounds in liquid and solid matrices. The technique is being used in increasingly more analytical laboratories in a variety of industries because it enables high sample turnaround, automated high-performance GC analysis, and automated and unattended sample clean-up by gas extraction, while avoiding laborious sample preparation. Static Headspace-Gas Chromatography provides the most thorough and current treatment available on this technique..
