Abstract: In a state in which a ferrule 10 is sandwiched and fixed between a ferrule receiving part 20 and a ferrule pressing part 30, the ferrule 10 is urged toward the ferrule receiving part 20 side by an urging member 33. With this structure, without configuring such that the ferrule pressing part is screwed in the ferrule receiving part by rotating several times, the ferrule 10 can be pressed toward the ferrule receiving part 20 side by a sufficient pressing force by the urging force of the urging member 33. Therefore, the attaching work of the column 2 can be performed more easily.

Abstract: 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.

Abstract: A ferrule 10 is pressed by a pressing plate 35, and the ferrule 10 is thereby sandwiched and fixed between a ferrule receiving part 20 and ferrule pressing part 30. The pressing plate 35 is displaced by a displacing mechanism 350, whereby the pressing plate 35 is switched between a contacting state in which the pressing plate 35 is in contact with the ferrule 10 and a non-contacting state in which the pressing plate 35 is not in contact with the ferrule 10 and the ferrule 10 can pass thorough the inside of the ferrule pressing part 30. By displacement of the pressing plate 35 to the non-contacting state, the ferrule pressing part 30 can be extracted from the ferrule 10 side, and the ferrule pressing part 30 can therefore be removed from a column 2 in a state in which the ferrule 10 is attached in a swaged fashion.

Abstract: 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.
