介绍了美国惠普公司的HP-4500感耦等离子体质谱仪的分析性能。列举了在常规分析条件时测定的灵敏度、背景计数以及检出限数据。通过地质标样的多元素分析和对照,考查了仪器的分析准确度和精密度。同时讨论了离子色谱(IC)和ICP-MS联用技术对高纯稀土分析的潜力。
The analytical performance of the HP-4500 inductively coupled plasma mass spectrometer from Hewlett-Packard in the United States is introduced. The sensitivity, background count, and limit of detection data measured at routine analysis conditions are listed. Through the multi-element analysis and comparison of geological standard samples, the instrument’s analysis accuracy and precision were examined. At the same time, the potential of high-purity rare earth analysis by ion chromatography (IC) and ICP-MS was discussed.
