Cryofocusing inlet with reverse flow sample collection for gas chromatography

An inlet system for high-speed gas chromatography is characterized, and a configuration for direct air sampling is described. A sample was cryofocused in a bare metal capillary tube and released by a fast temperature increase caused by an electric current.
