Claims

[Scope of utility model registration request]

A column in which a carrier gas flows, a plurality of sample collection tubes connected in front of the column, a controller for controlling the flow rate or pressure of the carrier gas flowing into the column, and a flow from a sample source to the plurality of sample collection tubes. a controller for controlling the flow rate or pressure of the sample;
It consists of a switching valve connected between the sample source and the plurality of sample collection tubes, and by switching the switching valve, the sample collected in the plurality of collection tubes is collected by a carrier gas. The sample source can be introduced into the column by a flow in the opposite direction, and the switching valve was originally designed to connect the sample source to the plurality of collection tubes, so that the sample could be introduced into the column through the plurality of collection tubes. Once collected in the tubes, by switching the switching valves, the samples collected in the plurality of collection tubes can be expelled by a carrier gas in the opposite direction to the flow during collection and introduced into the separation tubes. A gas chromatograph characterized by:
