土壤,岩石中微痕量元素的多元素光谱同时测定,国内外文献记载已有不少。近几年来,随着数学地质的发展及地质研究工作的规范化,地质部和冶金部均先后提出了分析土壤、岩石中33个元素的具体要求。要求对样品分析,不仅灵敏、快速,而且要准确、可靠。对这些要求,用传统的光谱方法很难满足,别的分析手段——如原子吸收、电化学等分析手段亦有困难,使用光电直读光谱仪,加上适当的条件,能较好地完成这任务。当然,任何一种分
Soil and rock micro-trace elements in the simultaneous determination of multi-element spectra, there are many domestic and foreign literature. In recent years, with the development of mathematical geology and the standardization of geological research work, the Ministry of Geology and Metallurgy have successively put forward the specific requirements for the analysis of 33 elements in soil and rock. Requires sample analysis, not only sensitive, fast, but also accurate and reliable. These requirements are difficult to meet with conventional spectroscopic methods. Other analytical techniques - such as atomic absorption and electrochemical analysis - are also difficult. Using a direct-reading optical spectrometer, coupled with appropriate conditions, can do this well task. Of course, any kind of points
