发射光谱分析具有操作简单,分析速度快,选择性好,能同时进行多元素测定的优点.但对于高含量元素的分析,光谱法的准确度较化学分析方法为差.随着电子技术的发展,出现了光量计.用光电倍增管代替了原来摄谱用的感光板,直接读取分析结果,消除了感光处理及测量过程带来的误差,使得光谱分析精密度有所提高.本试验使用光量计,对影响测定高合金钢准确度的诸因素进行了试验.选择最佳分析条件,进一步提
Emission spectrum analysis has the advantages of simple operation, fast analysis, good selectivity and simultaneous multi-element determination, but the accuracy of spectrometry is worse than that of chemical analysis for the analysis of high content of elements.With the development of electronic technology , The emergence of a light meter.Typical photomultiplier tube instead of the original photographic plate used directly read the analysis results, eliminating the photosensitive processing and measurement errors caused by the process, making the spectral analysis precision has increased.This experiment Light meter, the impact of the determination of high-alloy steel accuracy of the various factors were tested.Select the best analysis conditions, to further mention
