Compatible with all 9 mm screw-thread vials. Molded, 10-mil, solid pierceable cap. PTFE-free—ideal for PFAS analysis (e.g., EPA 537) and other PFAS-sensitive methods. Note: Polypropylene vials and caps prevent sample contamination from PTFE coated septa. However, since polypropylene caps do not reseal, evaporation occurs after injection.
There’s a Thermo Scientific screw top vial for every HPLC, GC, MS instrument, application, and budget. Our screw top clear and amber glass vials and plastic screw top vials are available in 8mm, 9mm, 10mm, and 13mm screw threads. The most commonly used vials are 9mm, 12x32mm screw thread vials.

Thread GC-MS Air/water check. %N2 higher when using headspace sampler. GC-MS Air/water check. %N2 higher when using headspace sampler Hello, When switching the column from front inlet (direct injection s/sl) to back inlet (headspace s/sl) I am getting a higher Nitrogen reading when performing the air/water check. Is there any obvious reasons
The laboratory vials used for headspace analysis are called headspace vials. The essence of this experiment is that the volatile sample is heated and volatilized to form a gas in the space on the top of the sample vials and then diffused. Eventually allowing the top gas in the gas chromatograph vials above the volatile sample to enter the gas
Headspace vials are available in several sizes (5-27 mL) and styles in clear or amber glass. The most common sizes are 6, 10 and 20 mL. The style and diameter of headspace vials will depend upon your autosampler.
The top finish of the vial can be a flat top or beveled finish. Using a beveled finish vial reduced the amount of sealing surface between the crimp seal and the glass surface
18mm Screw GC Headspace Vial is common element for each GC instrument. Sample handling in the overhead space is a convenient and fast sample pretreatment method in gas chromatography. In headspace analysis, the selection of sample vial is also critical.
Unlike crimp cap vials, Thermo Scientific™ National 18mm Screw Top Headspace Vials require no tools for closure. Manufactured with superior quality (Type 1, Class A) glass, they are available with a round bottom in sizes with usable volumes
Jul 02, 2019 · The more blank vials I run after my highest standard, the smaller the carryover peaks become. However, it is not time efficient for me to have to run 3 blanks in between standards in order to get decent peak shapes. GC Paramaters. OVEN. Initial: 60C (hold 0.1min) ramp to 300C (12.5C/min), hold 6 min. Carrier gas: Helium I am using Rxi-624Sil MS
