smoothly transports the vials to the six position incubator, where they are orbitally agitated at the user-programmed temperature. The heated syringe then samples the headspace and injects directly into the GC. The 2.5 or 5mL syringe is purged with inert gas after injection. The incubator oven and the heated syringe have the same programmable temperature range of 4-150oC. The rotating design leaves the injection port available for manual injections at any time. The HT200H processes samples so that headspace injections start immediately after the previous run is completed.
