Claims

[Scope of Claim for Utility Model Registration] (a) An outer tube into which the end of a capillary column is inserted and fixed at one end and a septum through which a microsyringe needle can be inserted is attached to the other end, and a cylindrical ring-shaped partition wall. an insert that is coaxially supported within the outer tube and whose open ends are located near the septum and near the end of the capillary column in the outer tube; a carrier gas supply conduit, the carrier gas supplied from the carrier gas supply conduit is passed from the opening end of the insert near the septum through the inside of the insert via a space formed by the inner wall of the outer tube and the outer wall of the insert. a sample injection section configured to be able to be introduced into the capillary column; (b) connected to the septum side end of the sample injection section so that gas remaining near the septum in the sample injection section can be purged out of the injection section; (c) a septum purge conduit with a flow rate adjustment mechanism connected to the capillary column connection section side of the ring-shaped partition wall setting position of the sample injection section, and the amount of carrier gas introduced into the capillary column; (d) an exhaust pipe branched from the carrier gas supply pipe via a switching valve, connected to the capillary column connection part side of the sample injection part from the ring-shaped partition setting position, and configured to control the supply carrier gas; A carrier gas branch supply pipe line capable of transferring a carrier gas to the capillary column and the exhaust pipe line. A sampling device comprising:
