为进一步提高单点修正激光诱导击穿光谱(OPC-LIBS)的定量分析精度,提出了基于萨哈-玻尔兹曼图与自吸收校正的OPC-LIBS方法,利用该方法对两个钛合金样品中的Ti、V和Al元素进行了定量分析,并将其定量结果与基于玻尔兹曼图的OPC-LIBS、基于萨哈-玻尔兹曼图的OPC-LIBS以及基于玻尔兹曼图和自吸收校正的OPC-LIBS的结果进行了对比分析。研究结果表明,所提出的改进方法在4种方法中可获得最小的定量误差,测量两个钛合金样品中3种元素的平均相对误差(MREs)分别为4。11%和3。99%,证明所提出的改进方法可有效提高OPC-LIBS的定量分析精度。
One-point calibration LIBS based on Saha-Boltzmann plot and self-absorption correction
To further improve the quantitative analysis accuracy of one-point calibration laser-induced breakdown spectroscopy(OPC-LIBS),the OPC-LIBS based on Saha-Boltzmann plot and self-absorption correction was proposed.Ti,V and Al in two titanium alloy samples were quantified using the method,and the quantitative results were compared with those of OPC-LIBS based on Boltzmann plot,OPC-LIBS based on Saha-Boltzmann plot,and OPC-LIBS based on Boltzmann plot and self-absorption correction.The results show that the proposed method can obtain the smallest quantitative error among the four methods,with mean relative errors(MREs)of 4.11%and 3.99%for the three elements in two titanium alloy samples,respectively,indicating that the proposed method can effectively improve the quantitative analysis accuracy of OPC-LIBS.
