Analysis method for trace harmful substances in polymer resin using matrix correction XRF method

摘要

The present invention relates to a method for analyzing trace harmful substances in a polymer resin using a matrix-corrected XRF method. In particular, compared to the conventional analysis, the standard sample and the analysis sample require a resin having the same or similar X-ray absorption rate, In the case of the present invention, it is possible to create a calibration curve even with different numbers, and analysis thereof is possible. Therefore, when the matrix-corrected XRF method of the present invention is applied, difficulties in preparing and securing a standard sample can be solved, and various polymer resins can be analyzed without difficulty.
