METHOD FOR ANALYZING X-RAY FLUORESCENCE AND METHOD FOR REMOVING BACKGROUND

摘要

The present invention relates to a method to analyze X-ray fluorescence and a method to remove backgrounds for the same, which accurately and efficiently removes backgrounds included in a spectrum for X-ray fluorescence analysis. A method to divide spectrum sections comprises: a step of creating a cumulative graph by performing multi-resolution analysis on spectrum data, and by collecting and accumulating differences of the analysis results; a step of detecting section division points by considering a gradient of the cumulative graph and the gradient rate; a step of dividing the spectrum data into sections based on the section division points; a step of firstly removing the backgrounds included in the spectrum data by classifying sections, where symbols of the differences of the analysis results are crossed and changes into a peak area, and the remaining sections into a background area; and a step of estimating the remaining background in the peak area and secondly removing backgrounds by fitting a beginning point and an end point of the peak area through a linear function or an exponential function.
