摘要
应用发射光谱法测定地球化学探测样品中的Ag、Sn、Mo。首先将样品和缓冲剂1:1混合,用光谱专用磨样机进行研磨,然后装入预先在车床上车好的电极中,用WPF-20型交直流电弧发生器,在WPP2型两米光栅摄谱仪上摄谱,最后在GBZ-Ⅲ型光谱相板测光仪上进行测量,计算,打印出样品结果。本方法具有固体粉末直接分析、可同时分析多个元素,分析检出限低,精密度好、操作简单、以及成本较低等特点。非常适合大规模的测定地球化学探测样品中的Ag、Sn、Mo。
Summary:Apply to shoot the spectrum method measurement geochemistry to probe into the Ag, Sn and Mo in the sample.Alleviate a blunt of sample first 1:1 mixture, use up table appropriation to whet kind machine to carry on grinding, then pack go into in advance get on the car good electrode in the lather in, hand over the direct current Hu occurrence machine with the type WPF-20, at wPPg type two meters only the grid shoot to compose instrument up shoot a table, finally in the GBZ- II type spectrum mutually the plank measure light instrument up carry on diagraph, compute, print out sample result.This method has direct analysis of solid powder and can analyze several chemical elements at the same time, analysis check a limit low, the sophistication is good, simple operation, and cost lower etc. characteristics.The very suitable large-scale measure- ment geochemistry probes into the Ag, Sn and Mo in the sample.
