Immediately to seal the vials, a magnetic crimp cap with a a silicone-PTFE septa product from Sigma Aldrich was used. To create a uniform solution, samples were shaken and then stored at -20°C. Headspace Solid-PhaseMicro-Extraction (HS-SPME) was performed for analysis of non-metabolite BTEX compounds in urine samples.
May 01, 2011 · A simple and reliable headspace GC‐flame ionization detection (HS‐GC‐FID) method has been developed and validated for the simultaneous determination of seven volatile compounds of forensic interest: sevoflurane, desflurane, ethanol, methanol, 1‐propanol, acetone and acetaldehyde. All seven compounds including acetonitrile (internal standard) eluted within 10 min and were well resolved
An aliquot of approximately 2 mL of the liquid extract was transferred to a crimp top GC vial and stored at −20°C until analysis. 2.4 GC×GC TOFMS parameters The GC×GC TOFMS system consisted of an Aijiren (Aijiren Technologies, Palo Alto, CA, USA) gas chromatograph and a Pegasus 4D TOFMS (LECO, St. Joseph, MI, USA) with quad jet

Aug 27, 2010 · Consequently, a small volume of the 0.5 N HCl solution (1.2–2.0 mL) was injected into the vial to adjust the pH to around 6 before 1 mL of headspace was extracted and injected into GC-MS. Chemicals 99.5% methanethiol and 0.5 N hydrochloric acid solutions were purchased from the Sigma-Aldrich Company (USA).
May 18, 2015 · Different sampling vials have been used to measure CH 4 and N 2 O in liquid and gaseous samples with GC. Samples can be stored in crimp sealed glass vials with volumes ranging between, e.g., 20 mL and 125 mL (Bastviken et al. 2010; DelSontro et al. 2011; Grossart et al. 2011).
All standard mix solutions were stored at 4–8 °C in amber crimp-neck vials. The mixture consisting of all the terpenoid standards was analyzed once a week in two concentrations to verify its stability. Whenever a decrease in over 20% of any of the signals occurred, the terpenoids mixture was freshly prepared.
Jun 11, 2020 · The vials were sealed with Teflon septa and crimp cap; vials were stored on their side to keep internal air space against the glass side, not the cap. After two and six week storage at 2–4 °C, aliquots were tested using the previously described procedure.

The bottles were closed with crimp seals (ND20, 10 mm centre hole, with bromo‐butyl/PTFE septa, Pharma Fix (Labsolute)).
Mar 12, 2020 · Dissolved gas samples should be stored without a headspace, as gaseous phase samples are more sensitive to pressure changes and consequent leakage. Gas samples stored in Exetainer™ vials have been shown to lose analyte to the atmosphere on monthly time scales, even under relatively constant storage conditions (Laughlin and Stevens 2003 ).
Thermo Fisher Scientific enables our customers to make the world healthier, cleaner and safer.
The samples were stored in self‐made headspace vials (10 mL) made out of polyetheretherketone. Vials and crimp tops (Cap BI 20 mm Si/PTFE, hole 8 mm; 45°, A 3 mm, VWR™) were dried before use at 60°C in a vacuum drying chamber (Binder, Tuttlingen, Germany) for 2 days.
