Multifunctional gas high-pressure in situ Raman test cell and application thereof

[0052] Example 1,

[0053] A multifunctional gas high-pressure in-situ Raman test cell, comprising an outer high-pressure cylinder 4, an inner high-pressure cylinder 8 is arranged in the outer high-pressure cylinder 4, and a window 5 is arranged at the front end of the inner high-pressure cylinder 8; The end of the inner high-pressure cylinder 8 extends outside the outer high-pressure cylinder 4, and is fixedly connected to the end of the outer high-pressure cylinder 4 through a fastener 14; the high-pressure gas source passes through the inner high-pressure cylinder 8 to the The front end of the inner high pressure cylinder 8 presses the sample 6 to the window 5.

[0054] Example 2,

[0055] A multifunctional gas high-pressure in-situ Raman test cell as described in Example 1, the difference is that a thermocouple hole 11 is provided in the outer high-pressure cylinder 4 for the insertion of the thermocouple.

[0056] A heating part is provided outside the outer high-pressure cylinder 4. The heating part is a heating tube 9.

[0057] An insulation layer 10 is also provided on the outer side of the outer high-pressure cylinder 4.

[0058] Example 3.

[0059] A multifunctional gas high-pressure in-situ Raman test cell as described in Example 1, the difference is that a height-adjustable base is provided at the bottom of the outer high-pressure cylinder 4. The height-adjustable base is made of insulating material.

[0060] The height-adjustable base includes a base 3, a connecting screw 1 and a fine adjustment nut 2.
