析設備に搬送する。Next, a procedure for collecting a sample liquid in the pneumatic jug 20 having such a structure on a sampling bench will be described with reference to FIG. First, the pneumatic feeding jug 20 is set on the side of the sampling device C containing the sample liquid S (a). The air pressure relationship will be described.
Is a pressure lower than the atmospheric pressure, that is, a relatively large negative pressure, the inside of the sampling device C is a relatively small negative pressure, and the surroundings are at the atmospheric pressure. This pressure relationship remains unchanged in the following description of the sample filling and filling process.
Next, the pneumatic jug 20 is moved to pierce the needle I of the sampling device C into the outer plug 27 (b). Since the pressure in the intermediate chamber 29 is higher than the pressure in the sampling device C because the pressure in the intermediate chamber 29 is atmospheric pressure, the sample liquid S inside does not enter the intermediate chamber 29. When the pneumatic jug 20 is further moved, the needle I penetrates the inner plug 25 (c). Since the pressure inside the main body 23a of the jug main body 23 is lower than the pressure inside the sampling device C, the sample liquid S is filled into the jug main body 23 through the needle I (d). Thereafter, when the pneumatic feeding jug 20 starts to be separated from the sampling device C, the tip of the needle I returns to the intermediate chamber 29 (e), but the sample liquid S does not enter the intermediate chamber 29 due to the aforementioned pressure relationship. When the pneumatic jug 20 is further separated from the sampling device C, the tip of the needle I is completely separated from the pneumatic jug 20, and the sampling of the sample liquid S is completed. The pneumatic jug 20 into which the sample liquid S has been put in this way is then conveyed to a sample analysis facility (not shown) through a pneumatic tube of a pneumatic facility not shown.

However, as in a pneumatic jug 30 shown in FIG. Liquid absorbing material 31 such as may be filled. By doing so, the above-described operation and effect can be obtained, and when the needle I is pulled out, the sample liquid adhered to the periphery of the needle I is wiped off, thereby further effectively preventing the outside of the pneumatic jug from being stained. Further, FIG.
When a similar liquid absorbing material and a rubber plate are put in the intermediate chamber 29 as in a pneumatic jug 40 shown in FIG. In any case, a material that does not give a large resistance to penetration of the needle is selected for the liquid absorbing material and the rubber plate.

A through-hole 57b may be formed, and a ventilation path leading to the intermediate chamber 29 may be formed on the outer peripheral surface. In this way, the through hole is not closed when penetrating the needle I as described above, and the pressure is unexpectedly communicated with the inside 23a of the main body, whereby the pressure of the sample liquid S is erroneously reduced. Leakage to 29 is effectively prevented. Further, if a projection 65a is formed on the inner side of the inner plug 65 and the outer plug 67 is fitted thereto as in the pneumatic jug 60 shown in FIG. 6, the outer plug 67 may accidentally come off and fall off.

The pressure inside the jug body was -9 mAq, the pressure inside the sampling device (in the needle) was -3 Amq, and the jig was stabbed into the needle of the sampling device, and in a test in which liquid was actually supplied, cerium nitrate on the outer surface of the plug was washed off. The concentration of cerium in the washing solution was measured by an inductively coupled mass spectrometer capable of measuring a very low concentration, and the amount of leakage was measured from the amount. Then, ten identical tests were performed for each example, and the average value and standard deviation of the leakage amount are shown in FIG. From the test results in this figure, the average of 1.3 × 10 in the comparative example (conventional structure) was obtained.
It can be seen that the leakage of -6 ml was reduced to about 1/4 of 4 x 10 -7 ml according to Example 1 of the present invention. Further, in Examples 2 and 3 in which a cloth as a liquid supply material or a polymer liquid supply material (brand name wiper wiper) was placed in the intermediate chamber, the leakage amount was further reduced, and each of the liquids was 1.6 × 10 −7 ml. And 2.3 × 10 −7 ml. Further, in Examples 4 to 6 in which a rubber plate was inserted between the liquid supply materials, the leakage amount was further reduced to 0.8 × 10 −7 ml.

With the plug side of the pneumatic jug after sampling set to the outside, an acceleration of 64 G was applied by centrifugal force. After the test, the amount of liquid adhering to the plug surface and the amount of scattering to the container containing the jug were measured.
The result is shown in the graph of FIG. The surface of the plug was washed once after sampling. The result is shown in FIG. As shown in FIG. 8, it can be seen that the amount of adhesion on the plug surface is reduced in the example of the present invention as compared with the comparative example (conventional type). It is considered that the increase in the amount of scattering was due to the very small amount of the sample liquid leaking into the intermediate chamber leaking from the through hole. On the other hand, when the liquid supply material is put into the intermediate chamber as in the second embodiment, the amount of adhesion and the amount of scattering on the plug surface are extremely small.
