Gas chromatography is used to separate sample components and remove background contamination prior to mass spectrometry. Columns are typically made of metal or fused silica and coated with a variety of liquid films; the liquid film is called the stationary phase. Packed columns, which are composed of metal or glass, can also be used in GC.

Presented here is a headspace-gas chroma-tography (HS-GC) method to quantify and identify VOCs in water-based coatings with very limited sample preparation and no solvent use. Headspace as a technique for analyzing VOCs in water-based coatings is often limited by the need to analyze for glycols. Within headspace, there are two common mechanisms for

Aug 28, 2022 · 5.1: Dynamic Headspace Gas Chromatography Analysis. Gas chromatography (GC) is a very commonly used chromatography in analytic chemistry for separating and analyzing compounds that are gaseous or can be vaporized without decomposition. Because of its simplicity, sensitivity, and effectiveness in separating components of mixtures, gas
