[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described below.

[0019] Example 1:

[0020] like Figure 1 As shown, this utility model proposes a contactless micro-powder dispensing tube, consisting of a glass storage tube 1, a silicone tube 2, and a glass conical tube 3 that run from top to bottom. By incorporating the silicone tube 2 into the contactless micro-powder dispensing tube, this utility model enables contactless dispensing and stopping of the sample, resulting in low cost and high operability. The end of the glass storage tube 1 is equipped with a detachable sealing head to prevent material leakage from the inlet during operation. Alternatively, the bottom of the glass storage tube 1 can be the inlet, with the bottom of the glass storage tube 1 detachably connected to the silicone tube 2, and then reconnected to the silicone tube 2 after the material is added.

[0021] Example 2:

[0022] This utility model also proposes a trace moisture analyzer, in which a glass conical tube 3 for non-contact micro-powder sample dispensing tube is inserted into the feed conical hole of the analyzer body 5. The conical surface can achieve a seal between the sample dispensing tube and the analyzer, avoiding interference from external moisture and achieving accurate measurement.

[0023] like Figure 2As shown, it also includes a double retaining ring 4, one ring of which is engaged with the outer circular opening of the conical hole in the analyzer body; the glass storage tube 1 can be fixed by the double retaining ring 4 in the detection and balancing stages to ensure the stability of the system.

[0024] The method for detecting moisture in particles and powders using the aforementioned trace moisture analyzer includes the following steps:

[0025] S1: As Figure 1 As shown, the sample to be tested is loaded into the glass storage tube 1, and the non-contact micro-powder dispensing tube and the sample to be tested are weighed together using a balance with a mass of 1 / 100,000 and the mass is recorded.

[0026] S2: As Figure 2 As shown, fold the silicone tube in half to ensure that the sample to be tested will not enter the analyzer. Insert the glass conical tube 3 into the conical hole of the analyzer body, and insert the glass storage tube 1 into the ring of the double retaining ring 4. Start the test in this state and wait for the instrument to balance.

[0027] S3: As Figure 3 As shown, after the instrument is balanced, start the sample injection. Pull the glass storage tube 1 out of the small hole of the double retaining ring 4 and place the contactless micro powder in a vertical position so that the sample to be tested can enter the analyzer. You can also gently tap the glass tube with your hand to allow more sample to enter the measuring cup.

[0028] S4: As Figure 4 As shown, bend the silicone tube 2 again to ensure that the remaining sample does not enter the analyzer during the detection process;

[0029] S5: Waiting for the analyzer to detect the moisture content of the sample;

[0030] S6: After the sample is tested, weigh the non-contact micro-powder dispensing tube and any remaining sample inside again. Figure 5 As shown, the mass of the sample entering the analyzer is calculated by the mass difference between the two measurements, thereby calculating its water content.

[0031] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
