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.
