摘要
Abstract
12 trace impurity elements, such as Mg, Al, Fe, Co, Ni and so on in high purity zinc is determined by glow-discharge mass spectrometry (GD-MS).The optimal working parameters for instrument is obtained, the reasonable sample pretreatment method and the interferential elements might be introduced is discussed, and the interference shall be eliminated by selection of the proper sample pre-sputtering time;the isotope mass spectral line interference existing in determination is discussed, and thus to choose the proper isotope mass spectral line and resolution mode for the elements to be measured, so the effect of interference can be minimized;the high purity zinc product sample is analyzed by Element-GD glow-discharge mass spectrometry with high resolution, the precision degree of determination is discussed, and the detection results are compared with the factory-calibration value, the results show, glow-discharge mass spectrometry is a kind of simple, accurate detection method for high purity zinc material.关键词
