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.

Blood Analysis for Ethyl Alcohol By Headspace Gas

Wipe the tip of the pipettor, place the tip in the appropriately labeled headspace vial and press the trigger once. This will dispense 250 µL of sample or calibrator into the vial, followed by 1 mL of the internal standard. The internal standard is diluted with sufficient
