摘要
在同步光源上 ,用PSS进行了高能量分辨率元素分析的可行性研究 .其结果是 :对含Ti和Cu的薄样品 ,绝对检测量可达 10 - 10 g级 ;对轻基体样品 ,Cr的探测限可达 1— 10ppm ;并且在含Cr的均匀液体样品中Cr峰面积积分净计数与其含量有良好的正比关系 .这些结果表明 。
The paper presents the study of feasibility on the trace element analysis with high energy resolution by PSS at synchrotron radiation as an exciting source. Results are that the absolute value of ～10 -10 g has been measured for elements of Ti and Cu in thin sample, the detection limit is about 1-10ppm order of magnitude for Cr in the substance of light base, and a well proportional relation exists between the counts of net integrated area and the concentration of Cr in the samples of homogenized solution. These show that the PSS is feasible as a useful tool to analyze element with high energy resolution.
