Abstract
A gas chromatograph with a chromatography unit (1) for chromatographic separation and analysis of a sample (2) and with a supply unit (3) that supplies the chromatography unit (1) at least with the sample (2) and with carrier gas (4). The two units (1, 3) can be interconnected via a connection interface (7), which is equipped with a gas connector (8) for the sample (2) supplied to the chromatography unit (1), a gas connector (9) for the carrier gas (4) supplied to the chromatography unit (1) and a sealing chamber (14) receiving the gas connectors (8, 9). The sealing chamber is purged with the carrier gas (4′, 4″, 4′″) that is used in the chromatography unit (1) for separation and is provided with an outlet (22) for the carrier gas (4, 4″, 4′″).
Claims7
A gas chromatograph, comprising:
- a chromatography unit chromatographically separating and analyzing a sample;
- a supply unit supplying the chromatography unit at least with the sample and with carrier gas;
- and
- a connection interface interconnecting the chromatography unit and the supply unit, the connection interface comprising:
- a gas connector for the sample supplied to the chromatography unit,
- a gas connector for the carrier gas supplied to the chromatography unit, and
- a sealing chamber, which receives the gas connectors and is purged with the carrier gas that is used for the chromatographic separation in the chromatography unit, and which comprises an outlet for the carrier gas.
A gas chromatograph, comprising:
- a chromatography unit;
- a supply unit supplying at least a sample to the chromatography unit;
- and
- a connection interface interconnecting the chromatography unit and the supply unit, the connection interface comprising:
- a first connector forming an entrance path for the sample from the supply unit to the chromatography unit,
- a second connector forming an entrance path for a carrier to the chromatography unit,
- a return path for the carrier from the chromatography unit, and
- a sealing chamber housing the first and the second connectors and the return path,
- wherein the return path is configured to discharge the carrier into the sealing chamber, and wherein the sealing chamber is configured with at least one outlet from the connection interface.
