The sample container (S) has an internal accommodating space for accommodating chemicals, and an inlet communicating with the internal accommodating space of the sample container (S) is formed at an upper end thereof. In addition, an openable and closable cap (C) is coupled to the inlet of the sample container (S). The cap (C) of the sample container (S) may be configured to be opened and closed by a screw method or a twist method.

9 is a view showing a state before the sample container is seated.

Referring to FIG. 9 , the cover 300, the cap opening/closing unit 400, and the nozzle unit 500 constituting the current sampling unit are raised together. In this case, the cover 300 may be spaced apart from the holder 210, and a space 261 for mounting the sample container may be formed between the cover 300 and the holder 210. In addition, the movable clamp 210b of the mounting unit 200 is retracted by the clamp advance and retreat part 220 so that the fixed clamp 210a and the movable clamp 210b are spaced apart, and between the fixed clamp 210a and the movable clamp 210b. A space 262 is formed in which the sample container is seated.

FIG. 10 is a view showing a state in which the sample container S is seated, the movable clamp 210b is advanced, and the cover 300 is lowered.

An operator may open the opening and closing door of the chamber 100 to seat the sample container S in the seating space formed by the mounting unit 210 and then close the opening and closing door again. And when the sample container (S) is seated, the clamp advance and retreat part 220 may advance the movable clamp (210b) in the direction of the sample container (S). In this case, the separation distance between the movable clamp 210b and the fixed clamp 210a is reduced, and the movable clamp 210b and the fixed clamp 210a may fix the sample container S at both sides of the sample container S.

Then, the sampling unit may descend to cover the top of the sample container seated on the holder 210 . Specifically, the cover 300, the cap opening/closing part 400, and the nozzle part 500 are integrally lowered by the sampling unit lifting unit 600, and the cover 300 may cover the top of the sample container S. there is. More specifically, as the cover 300 descends, the upper end of the sample container S including the cap C may be drawn into the inner space of the cover 300 ( 305 in FIG. 4 ).

In addition, as the cover 300 descends, the cover ring (371 in FIG. 4 ) formed along the inner circumferential surface of the cover 300 contacts the upper end of the sample container S, so that the lower surface of the cover 300 closes the opening 340. . In addition, one or more nozzle rings (351 and 352 in FIG. 3) come into contact with the nozzle (510 in FIG. 6) so that the side through hole 395 is sealed, and the upper surface through hole 320 through which the shaft 453 passes is also It is sealed by the blocking means. Therefore, the top of the sample container (S) is sealed by the cover 300, and the space 263 between the sample container (S) and the cover 300 may be blocked from the outside of the cover 300.

In addition, the remaining chemical or cleaning liquid remaining inside the nozzle 510 may be discharged to the outside of the chamber 100 through a drain port (335 in FIG. 3 ) and a discharge pipe connected to the drain port 335 .

In a state in which the top of the sample container seated in the mounting unit is covered, the sampling unit may close the cap of the sample container. Specifically, in a state in which the nozzle 510 is retracted, the opening/closing unit lifting unit 470 may lower the cap opening/closing unit 400 with respect to the cover 300 . Accordingly, the opening/closing unit elevating frame 473, the rotary driving member 460, the shaft 453, and the cap gripper 422 descend, and the cap C gripped by the cap gripper 422 moves toward the entrance of the sample container S. can be contacted with

Also, since the movable clamp 210b of the mounting unit 200 is retracted by the clamp advance and retreat part 220, the separation distance between the fixed clamp 210a and the movable clamp 210b may increase. In addition, the operator may open the opening and closing door of the chamber 100 so that the holder 210 may collect the sample container S or place a new sample container S on the holder 210 .
