Headspace vials are available in several sizes. The style and diameter of headspace vials depend on the autosampler. Vials with rounded bottoms are sturdier and more resistant to pressure than the flat bottom vial. The rounded bottom version was created to allow the vial, when transported by a magnet, to drop more easily into the heating block.

Recently a GC head space method has been developed and validated by a contract lab using a Perkin Elmer (HS 40) instrumentation. However, the headspace sampler ( ) and GC here are made by Aijiren. I have just learned that Aijiren headspace systems employ pressure loop system for sampling, whereas Perkin Elmer employ balanced pressure system. See more results

Jan 24, 2003 · To avoid band broadening, gas chromatography (GC) injection processes should introduce samples into the gas chromatographic flow-path as a short injection plug and in a brief lapse of time. This certainly requires practice [1] , [2] , combined with suitable instrumentation, sometimes fitted with special accessories.

This high performance instrument uses gas chromatography and electronic control while featuring an autosampler. This machine has a pressure regulator and single flame ionization detector(FID. It has controls for Hydrogen and Air. It is microprocessor controlled with no software included. If you have any further questions.

A rounded bottom is sturdier and thus more resistant to the high pressure within the vial during the heating process. In addition, the vial slides more easily into the heating block when being transported by a magnet. However, a flat bottom might be necessary when vials have to run within the instrument on a slightly downwards tendency.
