Headspace GC System
A headspace GC system combines controlled vial equilibration and gas-phase sampling with gas chromatography for suitable volatile compounds in liquid or solid matrices.
These pages describe technically coherent combinations of instruments and sample-preparation modules without assuming that every option is included by default.

A headspace GC system combines controlled vial equilibration and gas-phase sampling with gas chromatography for suitable volatile compounds in liquid or solid matrices.
A thermal desorption GC system collects or concentrates suitable airborne and material-emission compounds on a sorbent before controlled desorption into a gas chromatograph.
A pyrolysis GC system thermally decomposes non-volatile materials under controlled conditions and separates the resulting products by gas chromatography.
A GC gas supply solution is selected from the carrier-gas and detector-gas requirements of the actual chromatograph, detectors, method and simultaneous demand.
Laboratory gas supply planning aligns gas type, purity, flow, pressure, redundancy and safety with all connected instruments rather than a single nameplate value.
A post-column derivatization system adds a controlled reaction after HPLC separation when the target method requires a more detectable reaction product.
GPC cleanup separates high-molecular-mass matrix components from an extract before the collected fraction is analysed by GC or HPLC; it is not molecular-weight GPC analysis.
