Headspace Vials and Caps for Gas Chromatography
Headspace gas chromatography requires headspace vials and caps because they can withstand the pressure from the gas. Chrom Tech has a wide selection of high-quality crimp and screw thread headspace vials available in clear or amber glass with associated 18-and 20-mm headspace closures. Our headspace vials can be ordered as either flat or round
Headspace Gas Chromatography - an overview |
Several headspace systems are available; transfer to the gas chromatograph is with a gas sampling valve, a gas-tight syringe, or the pressure-balanced system that is unique to Perkin–Elmer [14]. Recently, commercial headspace samplers have become available with the capability of trapping the gas sample onto a sorbent instead of introducing it directly into the gas chromatograph.
