Chrom Tech carries a complete offering of GC vials, otherwise known as crimp style vials, for use with most gas chromatography autosamplers. Most GC laboratories use crimp top vials for GC applications due to their ability to seal well and accommodate highly volatile compounds. Nearly all gas chromatography vials require an 11mm closure and are

Figure 12.24 shows a typical example of a capillary column. Figure 12.24 Typical example of a capillary column for gas chromatography. This column is 30 m long with an internal diameter of 247 μm. The interior surface of the capillary has a 0.25 μm coating of the liquid phase. Capillary columns are of three principle types.

For example, if we’re analyzing methane at 0.5 to 1.8ppm, we would fill standard vials with N2 (0 ppm) and with a 5ppm standard. We can then correct the samples for any systematic change in the standards. We bring standards to the field in weakly pressurized gas canisters, or in Tedlar gas bags (Sigma-Aldrich an other vendors).

SureStop vials are designed for use with AVCS system screw caps. They improve transfer reliability and give a more secure liquid seal than standard screw vials. SureStop vials are available as a 2 mL as either clear or amber options and are highly recommended for use with GC and LC applications.
Mininert valves are very convenient for repetitive sampling and limit content exposure to the silicon septum. Models are available for screw-cap and crimp-top vials. The crimp-top valve for 20 mm ID glassware slides into the neck of the vial. Turn the threaded flange to secure a tight fit.
