Headspace GC (Gas Chromatography) vials are specialized sample vials used in headspace analysis. Headspace analysis is a technique used in analytical chemistry to analyze volatile compounds in a sample.
In headspace analysis, a sample is placed in a sealed vial, and the volatile compounds in the sample equilibrate with the headspace (the space above the sample) inside the vial. The vial is then heated to a specific temperature, causing the volatile compounds to vaporize and distribute themselves in the headspace.

Headspace vials are a type of laboratory vials used for gas chromatography analysis. They are designed to contain a small volume of sample and a headspace (the space above the sample) for the analysis of volatile compounds. These vials typically have a screw cap with a septum, which allows for the injection of a gas or a needle for sampling. The headspace vials are used to analyze volatile organic compounds (VOCs) in various samples, such as environmental, pharmaceutical, and food samples.
GC vials are typically made of glass or sometimes plastic, and they come in various sizes and shapes to accommodate different sample volumes and injection methods. They often have a screw cap with a septum, which allows for the injection of the sample or a needle for sampling.

20mm crimp-top headspace vials are a type of laboratory vials commonly used in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) applications.
These vials are specifically designed for the analysis of volatile compounds in samples.
Headspace analysis is used when analyzing volatile or semi-volatile compounds that can be released from a solid or liquid sample into the gas phase.
This technique is particularly useful for samples that would be difficult to directly inject into a GC system or when analyzing volatile compounds in complex matrices.

Pre-slit Crimp-top Cap with butyl/PTFE silicone GC vial septa are commonly used in gas chromatography applications to provide a reliable and inert seal for sample vials.
These septa are typically composed of three layers: a butyl rubber backing, a PTFE (polytetrafluoroethylene) middle layer, and a silicone top layer.
When purchasing septa, it’s important to ensure that they are compatible with your specific GC vials and instruments.
