Referring to FIG. 3, the function of the auxiliary injection needle 200 shown in FIG. 4 will be described in more detail as follows. A sample is sampled by the pressure difference between the cylinder 110 and the vial 10, which requires more force to collect a large amount of sample. This is because the sample in the vial 10 moves to the cylinder 110, thereby lowering the pressure of the vial 10. At this time, the auxiliary injection needle 200 can keep the pressure in the vial 10 equal to the atmospheric pressure or the pressure in the chamber by injecting the outside air into the vial 10. As a result, a pressure difference between the cylinder 110 and the vial 10 is generated, so that the sample can be collected more easily.
