crimping headspace vials with patch for gas chromatography

1999/10/22 · Chromatography was initiated with a non-split injection on a packed column injector at a flow-rate of 6 ml/min of helium as a carrier gas. A minimum flow-rate of 0.2 ml was received from the GC packed column injector to prevent the sample from backing up into the injector lines during injections from the headspace autosampler.

The volatile THF contained in the urine is determined using headspace capillary gas chromatography. For this purpose, the urine samples are heated in gas-tight sealed crimp cap vials to 40 C. When partition equilibrium of the tetrahydrofuran between liquid and

2015/7/31 · 2.3. Headspace sampling and gas chromatography The analyses were performed using a HS 40 XL autosampler (Perkin Elmer, Waltham, MA, USA) connected to Focus GC with FID detector (Thermo Scientific, Rodano Milan, Italy). The GC column used was

Vial blank samples were prepared by capping the empty 20 mL headspace crimp top vials or screw top vials directly; no effort was made to purge the vials with an inert gas prior to capping. These vial blank samples were used for blank background and potential septa contamination evaluation.
