Abstract

The invention relates to a tungsten-nickel powder glow discharge mass spectrometry detection method, which comprises: (1) placing tungsten-nickel powder in a sample pit of an indium sheet and levelling the top surface, and pressurizing to obtain a sample to be detected; (2) putting the to-be-detected sample obtained in the step (1) into a sample chamber in a glow discharge mass spectrometer, fixing the to-be-detected sample by using a sample clamp, vacuumizing by using an ion source, pushing the to-be-detected sample into a discharge chamber, setting the discharge current to be 1-3mA, the discharge voltage to be 1-2kV and the resolution to be 3400-4000 in a direct-current mode, collecting the signal intensity of the to-be-detected element, and calculating the mass fraction of the to-be-detected element by using the relative sensitivity factor. According to the detection method, by setting the test parameters, a strong test signal can be obtained, and the sensitivity is high.
