Headspace Oxygen in Sample Vials Affects Volatiles Production

Jun 18, 1999 · Headspace oxygen in sample vial for the purge-and-trap dynamic headspace/gas chromatography method oxidizes meat if held hours before purging, influences volatile profiles, and misrepresents the true composition of volatiles. Helium flush and helium flush plus oxygen absorber were used to eliminate residual oxygen and minimize oxidative changes in meat during sample holding time. Both helium

Sample Preparation Techniques for Gas Chromatography | IntechOpen

Apr 02, 2019 · In gas chromatography (GC), the sample is vaporized and injected onto the head of a chromatographic column. Elution is brought about by the flow of an inert gaseous mobile phase such as helium, argon, nitrogen, carbon dioxide, and hydrogen. In GC, the mobile phase does not interact with molecules of the analyte, and it only transports the analyte through the column. In two general kinds of GC

Calculating the headspace concentration - Chromatography Forum

Oct 10, 2018 · Heat the vial above the boiling point of everything in the vial (solvent must boil less than the ndma in this case). Use a heated gas-phase syringe to make your injection. In theory, if you have 22 µg of ndma in a 22 mL headspace vial and you inject 1 mL of gas from the vial, then you'd be injecting 1 µg of ndma into the gc.
