Problems with Headspace GC - Chromatography Forum

Apr 08, 2018 · Sample is 100mg of SSG in 20mL headspace vial. Add 5.0mL of DMSO. Please note that this has happened about a week ago. I thought I clogged the headspace autosampler and I cranked the oven, loop, and transfer line up to 150, 160, 170 each to try to get whatever out. It was giving me nice peaks but then all of a sudden no more peaks. Thanks Jeff

Aijiren Network Headspace Sampler

The Headspace Sampler eliminates this problem with its nonreactive, nonadsorptive sample flow path from the point of sampling through injection. This significantly reduces carryover – a common problem with older instrumentation. The following examples demonstrate how the flexibility of the HSS allows use in multiple applications.

Aijiren Headspace Sampler Versus an Aijiren A

The default fill mode is Fill at flow to pressure. The headspace uses a fixed flow rate to pressurize the vial to a specified level. In the default Loop Fill Mode, the headspace uses the initial vial pressure to calculate an optimum flow rate and final vial pressure for filling the sample loop. The user can learn more about the different modes

Aijiren Headspace Sampler - Florida International University

After a programmed heating time, the headspace gas is extracted from the vial and injected into a GC for analysis. There are two means of extracting the headspace gas from the vial—single or multiple headspace extraction (MHE). With single headspace extraction, only one sample of gas is taken from each sample vial. Single headspace extraction

Preparing Headspace Vials - Chromatography Forum

Mar 08, 2012 · Preparing Headspace Vials. We are using 10mL headspace vials with gray butyl septa (boiled prior to use to clean and prevent leaking) and capped with aluminum crimps to store 12mL atmospheric gas samples. We will be measuring CH4, N2O, and CO2 on a GC with an FID, ECD, and TCD, respectively. Our GC carrier is He.
