Embodiment 1
[0051] This embodiment discloses a gravimetric gas adsorption test device, such as Figure 1-3 As shown, it includes a detection component, one end of the detection component has an inlet, and the detection component has a closed sample holding chamber, the sample holding chamber is used to place the sample to be tested, and the inlet is connected to the sample holding chamber cavity, the detection component is provided with a filter membrane, and the filter membrane is located between the inlet and the sample to be tested.
[0052] In this embodiment, the sample holding chamber is set to be airtight, and the test device can withstand a pressure of up to 200 Bar; by setting a filter membrane in the sample holding chamber, the sample to be tested is always in a stable and clean space, preventing the The sample to be tested is blown away by the high-pressure airflow during the air and air intake process. The test device is capable of high-pressure gas adsorption test, and compa...
Embodiment 2
[0067] refer to Figure 4 It should be understood that the sample compartment 10 of the gravimetric gas adsorption testing device of this embodiment is a hollow and elongated cylindrical structure, the interior of the sample compartment 10 forms a sample holding chamber, and the inlet is located on the left side of the sample holding chamber. By adopting the above-mentioned structural form, the effective volume of the sample holding chamber is greatly increased under the condition that the outer surface area is as small as possible.
[0068] There is a VCR joint 503 at the inlet, and the filter membrane is set inside the VCR joint 503, wherein the filter membrane is set inside the VCR joint 503, which can prevent the light sample to be tested from being brought to the position of other parts by the airflow during the inflation process Contaminate and affect test results.
[0069] The gravimetric gas adsorption testing device also includes a four-way joint 90, the first end of...
