Jul 6, 2022 · Headspace vials are divided into two categories – threaded headspace vials and crimped headspace vials. As the name implies, the main difference between them is the different fitting methods. Generally, the sealing performance of the screw is slightly better than that of the jaw, and the screw is more convenient for manual operation, while

Headspace analysis is a technique for sampling and examining the volatiles associated with a solid or liquid sample. The actual headspace itself is the volume of vapor or gas above the sample. For most headspace analysis purposes the sample and its associated headspace are held within an enclosed container (Figure 1 ).

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.
It is important to ensure the correct vial and cap are used! Vial Size: Headspace vials are available in 6, 10 and 20 ml sizes. Use a vial large enough to ensure adequate headspace or phase ratio without excessive dilution of the components of interest. Phase ratio is discussed later and should normally be at least 50 % of the sample volume.
Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can accommodate virtually any matrix.
Aijiren headspace vials come in two sizes, 10 mL, or 20 mL in either clear or amber glass. Available in flat or round bottom designs, and feature a bevelled top for maximum level of seal security. Aijiren headspace crimp caps are 20 mm and are engineered to provide consistent secure seals.
These headspace vials offer excellent performance. Caps are blue polypropylene. Butyl stoppers can be used when PTFE is not required. Butyl/PTFE septa are an economical choice with low background peaks. Molded PTFE/butyl septa offer the tightest seal of all PTFE items, as well as low background peaks.
