上海冶金研究所在全国有色金属系统发射光谱和x-荧光光谱学术报告会上作了“氢化物感应耦合等离子体发射光谱法测定微量锡和锗”的研究报告。国外将气态氢化物引入原子吸收、原子荧光和等离子体发射光谱,分析了铋、硒、砷、碲、锑、锗、锡等几个元素。国内近几年用氢化法进行了原子吸收分析,但将气态氢化物引入感应耦合等离子体进行发射光谱分析还未见报导。上海冶金所在报告中介绍了将试样溶液和硼氢化钠溶液分别用蠕动泵引入气液分离器中,所产生的气态氢化物(SnH_4,GeH_4)在焰炬中进行Sn和Ge的激发分析。作者采用GP3.5-D1型等离子发生器(最大功率3.5KW,
Shanghai Institute of Metallurgy at the National Nonferrous Metals System Emission Spectroscopy and x-fluorescence spectrometry report made at the “Hydride Inductively Coupled Plasma-Atomic Emission Spectrometry Determination of Trace Tin and Germanium,” the research report. In the foreign countries, gaseous hydride is introduced into atomic absorption, atomic fluorescence and plasma emission spectroscopy, and some elements such as bismuth, selenium, arsenic, tellurium, antimony, germanium and tin are analyzed. Atomic absorption analysis has been carried out in China in recent years by using hydrogenation method. However, the introduction of gaseous hydride into inductively coupled plasma for emission spectroscopy has not been reported yet. Shanghai Metallurgical reported in the report that the sample solution and sodium borohydride solution were respectively introduced into the gas-liquid separator by using a peristaltic pump, and the produced gaseous hydrides (SnH4, GeH4) were used for the excitation analysis of Sn and Ge in the torch. The author uses GP3.5-D1-type plasma generator (maximum power 3.5KW,
