国产7502型ICP—AES光量计在地质样品分析中的试用

我们试用了北京第二光学仪器厂新近研制成功的7502型ICP—AES光量计。用于地质样品分析,进行了硅酸盐类样品中24个元素的同时测定。对该仪器的计算机软件提出了较大的修改,使其能适应于各种类型样品分析。实验结果表明,该仪器在检出限、精确度方面都达到或超过国外同类仪器的水平。这标志着我国的大型精密仪器已跨入世界仪器制造业的先进行列。我们很高兴地向国内的主管部门和同行们推荐该新产品。 本工作仅对硅酸盐类样品进行测试。采用HF,

A Trial of The 7502 ICP Direct Reader in The Analysis of Geological Samples

The 7502 ICP Direct Reader was recently manufactured by Beijing Second Optic Instruments ractory. A trial of this instrument was made in the analysis of geological samples, 24 major, minor and trace elements were determined simul- taneously. Both linear and nonlinear interference corrections could be made by maans of a computer to correct the interelement line and background interfere- nces. The performances of this sophisticated instrument appeared to be good and both detection limits and precisions are close to or occasionally better than si- milar foreign instruments.
