Summary: | The utility model belongs to the technical field of loading devices. The utility model relates to a device, in particular to a device for measuring non-conductor powder by a glow discharge mass spectrometer. Included is a cylindrical base, a mold is arranged at the top of the cylindrical base; a through hole is formed in the center of the top of the mold; a pressing rod is inserted into an inner cavity of the through hole; the top of the pressing rod is in threaded connection with a cylindrical pressing head; pressing the non-conductor powder into a mold hole made of high-purity tantalum; high-purity tantalum is used as a second cathode of a glow discharge ion source; the problem that GD-MS (Gas Chromatography-Mass Spectrometer) detection cannot be carried out on non-conductor powder due to non-conduction is effectively solved; a sample prepared by using the loading device is smooth in surface; the sample preparation device has good pressing strength, is not easy to fall off, effectively avoids the risk that |
