Static headspace is one of the most popular techniques due to its versatility for analyzing volatile organic compounds (VOCs) in a complex variety of matrices. This is due to the elimination of tedious sample preparation steps and prevents contamination problems that are common to other sample introduction techniques.

Headspace gas chromatography uses headspace gas—from the top or "head" of a sealed container containing a liquid or solid brought to equilibrium —injected directly onto a gas chromatographic column for separation and analysis.

Aijiren / B/ headspace-gas chromatography-mass selective detection (HSS-GC-MSD) system with concomitant flame ionization detector (FID) detection using integrated Capillary Flow Technology to split the column effluent in a controllable and precise manner to the two detectors.

OQ/PV headspace sample standard contains 0,2 to 0,3% t-butyl disulphide, 1,2-dichlorobenzene, and nitrobenzene in ethanol.

1.1 This test method covers the determination of glycol based antifreeze for in-service engine oil by derivative headspace/gas chromatography. 1.2 Sample is derivatized in-situ directly in a headspace sampling vial prior to vapor phase extraction and injection into a gas chromatograph.

Apr 01, 2016 · How does gas chromatography work? Like for all other chromatographic techniques, a mobile and a stationary phase are required for this technique. The mobile phase (=carrier gas) is comprised of an inert gas i.e., helium, argon, or nitrogen.

I cap a headspace vial and fill it with a calibration gas by inserting two needles into the septum. One needle is long and reaches to the bottom of the vial and through this needle the gas is flowing. A second short needle is inserted in the septum to allow the gas to escape and flow to occur.

Headspace Analyzer. The increased temperature causes the volatiles to be released from the solution into the “headspace” above the liquid. The headspace is then sampled and analyzed for the presence of the targeted analytes via gas chromatography. g% = g/dl; e.g. 0.08g% = 0.08g of alcohol in 100ml of blood same as 0.08g/dl .
