ICP EMISSION SPECTRAL ANALYSIS METHOD IMPROVED IN ANALYSIS ACCURACY

摘要

PROBLEM TO BE SOLVED: To provide a method for correcting an analysis error due to ionization interference with a simple method and acquiring a quantitative value having high analysis accuracy in quantitative analysis using an ICP emission spectral analysis method.;SOLUTION: There is provided the ICP emission spectral analysis method configured to add a sodium compound and/or potassium compound to a reference sample solution for creating a calibration curve or both of the reference sample solution and a measured sample solution, so that density of sodium and/or potassium becomes almost equal in both solution, in the reference sample solution and the measured sample solution.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
