Aijiren Tech™ headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs. Product Overview
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.
The Aijiren Headspace Sampler ensures each vial is leak-free prior to analysis, with no loss of precision or sensitivity. The Aijiren Headspace Sampler is based on the architecture of the market leading GC and Automatic Liquid Sampler line of products. Features include Automatic Leak Check, which ensures each vial is leak-free
The new design of the TriPlus 500 Headspace Autosampler incorporates innovative features for highly accurate analytical results, including: New pneumatic controls for high precision and robustness Best injection repeatability for consistent results at every run. No carryover due to effective sample path purging.
Aijiren Tech 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 Aijiren Tech SureStop vials to get maximum benefit of the two technologies.

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.
a 20-mL headspace vial. Ethylbenzene (EB), cumene, and styrene monomers (SM) are discussed here. Therefore, 2 µL DMF solution containing 10% v/v EB, cumene, and SM was transferred in a 20-mL headspace vial as an external standard. Configuration All experiments were performed using a Headspace Sampler (HSS) with a A GC. The A GC was
Headspace analysis permits the detection of volatile substances in a liquid or solid sample and minimizes column contamination. A small volume of the sample is placed in a vial sealed with a septum and the sample vial is equilibrated at an appropriate elevated temperature.
Headspace vial caps are available in a variety of materials including aluminum, bimetal, and steel; headspace vial cap septa are available in PTFE/silicone, molded PTFE/butyl, and high-temperature varieties. Our headspace vial caps come in either 11 mm, 18 mm, 20 mm or 22 mm sizes. Most used headspace vial caps are crimp cap style.
These headspace vials offer excellent performance.Vials are available in all capacities, materials like plastic vials or glass vials, and in a variety of colors to meet any collection, storage, or analysis need. Tailor vessels for specific media with various translucent manufacturing and different sterility options for precise test results. Choose from the extensive selection featuring
DWK Life Sciences (Wheaton) Wheaton headspace vials accept 20 mm aluminum seals Rounded shoulders and bottoms, allowing for even heating and safer operation at higher pressures Manufactured from Type I borosilicate glass Top provides a tighter seal with your septa O.D. x Height: 22 x 38 mm Capacity: 6 mL.
vial by sampling it and injecting it into the GC for analysis. The presence of agent in the outer vial indicates that it has permeated through the film. Multiple sampling can be used to determine time dependence. Solids can also be used in the headspace vial without the inner vial. 15. SUBJECT TERMS
Headspace vials are common for analysis of volatile organic compounds, such as blood alcohol content, pharmaceuticals, and food flavoring analysis. The analytes of interest can be isolated in the gaseous phase, so the gas from the headspace portion of the sample vial is injected onto the GC column. For this reason, a larger vial is required
