Abstract

PURPOSE:To make it possible to cancel effectively the effect of the sample residue by arranging two fluid inlets and one fluid outlet in the sample injecting chamber, and constructing a flow-route select mechanism to change the fluid inlet and a closing mechanism for the flow outlet. CONSTITUTION:A sample is led into a sample injecting chamber 1 through a rubber stopper 5 by an injecting needle, and sent to a column 3 and a detecter 4 by carrier gas introduced from a carrier gas inlet 2 through a flow-route switching valve 7. At this time, a stop valve 12 connected to a gas outlet 10 is closed. Therefore, the sample is sent to the column 3. A part of carrier gas flows all the time to the sample injecting chamber 1 through a flow-route resistance 8. When all the sample reaches at the column 3, the stop valve 12 is opened and the flow-route switching valve 7 is switched. Flow of carrier gas is divided to the column and to the gas outlet 10. High boiling point residue left in the chamber 1 after injecting the sample is exhausted through the gas outlet 10 by a part of carrier gas. The sample in the column 3 is sent to the detecter 4 by the other part of carrier gas.
