Gas chromatography (GC) is a technique used to separate and analyze compounds that can be vaporized without decomposition. There are many gas chromatography applications. The method is widely used in environmental testing, forensic science, and pharma R&D and QC applications.

Separation Science offers free learning from the experts covering methods, applications, webinars, eSeminars, videos, tutorials for users of liquid chromatography, gas chromatography, mass spectrometry, sample preparation and related analytical techniques.

An Introduction to Headspace Sampling in Gas Chromatography Phase Ratio Other factors that can affect the concentration of an analyte in the headspace phase are the respective volumes of the sample and the headspace in the sealed vial. The concentration of analyte in the sample and the headspace can be expressed respectively as Equations 2 and 3.
