Gas chromatograph for chromatographic separation and analysis of sample comprises chromatography unit and supply unit connected to each other via connecting point having gas connectors and sealing chamber

摘要

A gas chromatograph comprises a chromatography unit (1) for chromatographic separation and analysis of a sample (2), and a supply unit (3) supplying the chromatography unit at least with the sample and a carrier gas (4). The two units are connected to each other via a connecting point (7) having a gas connector (8) for the sample, a gas connector (9) for the carrier gas, and a sealing chamber (14) receiving the gas connectors. The sealing chamber is flushed with the carrier gas and has an outlet (22) for the carrier gas. Preferred Features: The supply unit has a sample evaporator (15) for liquid samples.
