fabrics, films, and other solid materials. Headspace GC or GC/MS instrumentation is used. A vial in a vial method is used, in which the volatile agent is placed in a small inner vial, and the inner vial is capped with a layer of fabric or film to be tested. The agent permeates from the inner vial into an outer headspace vial.

Thermo Scientific Advanced Vial Closure System (AVCS) caps are polypropylene caps that are compatible with all 9 mm short thread screw vials, although we recommend that they are used with our Thermo Scientific SureStop vials to get maximum benefit of the two technologies.

This method uses headspace gas chromatography (HSGC) for analysis of miscellaneous volatile compounds in biological specimens such as blood, serum, vitreous humor, urine, tissue homogenates and gastric content.

3.9.3 Headspace gas chromatography. Headspace GC is a sampling technique that involves the indirect determination of volatile constituents in liquid or solid samples by analysing the vapour phase that is in thermodynamic equilibrium with the sample in a closed system [149, 150]. It is used predominantly for the determination of volatile

The vials are used to heat the sample until the concentration of the liquid and gas phases are in equilibrium. phases are in equilibrium.

There are three states of matter under these conditions: solids, liquids, and gases. Although all three are distinct states, both solids and gases can dissolve (or disperse) in liquids. The most commonly occurring liquid in the biosphere is water. All components of the atmosphere are capable of dissolving in water to some degree.

Headspace vials for gas chromatography, come with crimp top 22mm and available in different sizes. Headspace vials are available with flat and rounded bottom. Can be used in combination with standard aluminum seals, magnetic seals or pressure release seals.

With the use of headspace vials, the whole experiment can be prepared for analysis in an efficient and accurate way. The essence of this experiment is that the volatile sample is heated and vaporized to form a gas in the top space of the headspace vial and then diffuses.

Headspace vials often come in larger volumes than the 2-mL vials used in many liquid sampling systems. Common offerings are 10-mL, 20-mL and 22-mL capacities. Larger vials accommodate larger sample volume and/or a larger headspace above that sample.
