摘要
激光诱导离解光谱技术作为一种物质元素分析手段,其主要目的是用来提供高精度的定量分析.通过分析传统定量化方法的不足之处,提出了基体校正法.此方法有效地减少了基体效应对测量结果带来的影响,放宽了对标准样本的要求,扩大了适用范围,并通过实验验证了此方法应用于激光诱导离解光谱技术定量化工作的可行性.
Abstract
Laser induced breakdown spectroscopy (LIBS) is an elemental analysis technique. Its ultimate goal is to provide a highly quantitative analysis. Matrix correction method was put forward to compensate for the deficiency of the traditional quantitative method. This method is effective in reducing the impact of matrix effect on the measurement results. The limitation of standard samples is relaxed, and the scopes of application are expanded. The feasibility of the method applied to quantitative analysis of LIBS is tested by experiments.
