Keyword激光诱导击穿光谱 定量分析 分析线 自吸收 谱线重叠
Abstract为了实现激光诱导击穿光谱分析中的分析线自动选择,定义了元素发射谱线的相对强度比(RDTIR)、波长偏差(WDDT)两个参数,并据此对检测谱线进行筛选,通过设定合理的阈值,剔除自吸收和干扰严重的谱线。通过对高合金钢(GBW01605)实验数据的分析,分别选定了样品中主要元素铁、铬、镍、锰、铜的分析线,选线结果符合谱线的选取原则。
Other AbstractTo realize auto-selection of analytical lines for quantitative analysis of materials with laser-induced breakdown spectroscopy,two parameters,i.e.the relative detected-to-theory intensity ratio(RDTIR) and wavelength difference of detected and theory(WDDT) were defined.The spectral lines seriously disturbed by self-absorption and spectral interference were excluded automatically by setting reasonable thresholds of RDTIR and WDDT.By analyzing the experimental data of high-alloy steel(GBW01605),the analytical lines of iron(Fe),chromium(Cr),nickel(Ni),manganese(Mn) and copper(Cu) were selected,and the results were in line with the principle of lines selection. 更多
