What is Headspace Analysis Gas Chromatography?

Static Headspace gas chromatography is a technique used for the concentration and analysis of volatile organic compounds. For cannabis, headspace sampling is used to extract and analyze specific cannabinoids from a cannabis sample. In simpler terms, after identifying cannabinoids and terpenes from a sample, headspace sampling is used to further analyze those segments.

Agilent 7697A Headspace Sampler

This model can hold up to 111 vials and can be programmed to process each sample autonomously. It also has 3 "priority positions" that allow users to insert a sample that takes precedence over others without having to completely redo the sample order. It uses a barcode reader to track individual vials and has an interface to make it the process easier for users who are unfamiliar with headspace sampling. For advanced users, the interface allows you make new testing techniques and make preprogrammed solutions for things that can go wrong.

The oven holds up to twelve vials but has individual chambers so samples can start at different times. The individual vials can also be preprogrammed by the interface so they go in and out of the oven at the correct times. It is also compatible with other systems in the Agilent 7600 Series.
