Example Embodiment
[0051] Example 1
[0052] This embodiment provides a glow discharge mass spectrometer detection method of tungsten nickel powder, the detection method comprising the steps of:
[0053] (1) The tungsten nickel powder is filled with the sample pit of the indium sheet using a polytetrafluoroethylene picker. The SYP-30TS manual pressurch is pressurized, and the pressure of the pressurized pressure is 10 MPa, and the time is 10 min. Get the sample to be tested;
[0054] Among them, the indium sheet is compressed by molten metal indium, which is cooled; the indium sheet is a circular cake, and the sample pit is a cylindrical shape, and the indium sheet is coincident with the center of the sample pit; the indium; The thickness of the sheet is 2 mm, the diameter of the sample pit is 0.7 mm, and the depth is 0.3 mm;
[0055] The indium sheet with a sample pit is cleaned before the tungsten nickel powder is placed in a sample pit of the indium sheet, and the cleaning treatment comprises pla...
