Aug 2, 2022 · There are a few different types of headspace sampling, the first being the simplest: Syringe Injection. This is where a gas-tight syringe is used to withdraw a small volume of vapor from the headspace of a vial that has been heated and inject it into a GC split inlet.
These headspace vials are made to withstand higher temperatures and internal pressures required for volatile gas analyses. They have very low metal content, extractables, and leachables and conform to high standards to meet your regulatory requirements.

Basic principles of headspace analysis. A headspace sample is usually prepared in a vial containing the sample, the dilution solvent, a matrix modifier and the headspace. Volatile components from complex sample mixtures can be extracted from non-volatile sample components and isolated in the headspace or gas portion of a sample vial.
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.
