A gas chromatograph includes a sample introduction portion and a heater block. A contact portion is fit into a first recess of a main body of the sample introduction portion. The heater block is fixed to and positioned with respect to the main body of the sample introduction portion by directly coming into contact with the contact portion provided on the main body of the sample introduction portion. For this reason, the heater block may be securely positioned with respect to the sample introduction portion.

Gas chromatograph

In a state in which a ferruleis sandwiched and fixed between a ferrule receiving partand a ferrule pressing part, the ferruleis urged toward the ferrule receiving partside by an urging member. With this structure, without configuring such that the ferrule pressing part is screwed in the ferrule receiving part by rotating several times, the ferrulecan be pressed toward the ferrule receiving partside by a sufficient pressing force by the urging force of the urging member. Therefore, the attaching work of the columncan be performed more easily.

Column-attaching device and ferrule set

A housing is provided with an internal space for accommodating an insert and a cylindrical cap attachment part provided, at the distal end surface thereof, with an opening part communicating with the internal space. An inclined groove that is inclined from the distal end side to the proximal end side of the cap attachment part along the circumferential direction of the cap attachment part is provided on the outer circumferential surface of the cap attachment part. A cap fixing part for attaching a seal cap to the cap attachment part has a cap holding part for holding the outer peripheral surface of the seal cap and an elastic part connected to the cap holding part. The elastic part is provided with a protrusion that is fit into the inclined groove of the outer peripheral surface of the cap attachment part.

A ferruleis pressed by a pressing plate, and the ferruleis thereby sandwiched and fixed between a ferrule receiving partand ferrule pressing part. The pressing plateis displaced by a displacing mechanism, whereby the pressing plateis switched between a contacting state in which the pressing plateis in contact with the ferruleand a non-contacting state in which the pressing plateis not in contact with the ferruleand the ferrulecan pass thorough the inside of the ferrule pressing part. By displacement of the pressing plateto the non-contacting state, the ferrule pressing partcan be extracted from the ferruleside, and the ferrule pressing partcan therefore be removed from a columnin a state in which the ferruleis attached in a swaged fashion.
