【摘要】 <正> 感应耦合高频等离子体(ICP)最初是Reed于1961年开始研究的,他在研究大气压力下维持电离气体(等离子体)的新方法时,根据感应加热的原理使等离子体感应产生高频涡流。1964年Greenfield等把等离子体作为激发光源首先应用于发射光谱分析。不久Wendt和Fassel也报道了他们的研究情况。高频等离子体光源的出现,由于它具有无可比拟的优点,使发射光谱的发展获得了新生,被广泛应用于化工、地质、冶金、材料以及环保分析中。更多还原

【Abstract】 Since 1975 inductively coupled high frequency plasma for emission spectrometry have been studied in our laboratory, The ICP device was assembled and constructed. The perfomances of ICP emission spectrometry analysis were studied. The optimum working condition was looked for and the detection limits for some elements under the optimum condition were determined. And the application of the ICP source with desolvation apparatus or without it to analyse aluminum alloys, low alloy steels, high purity quartz and chemicals, semiconductor materials, drinking water and rice were carried out. Satisfactory results have been obtained.更多还原
