METHOD FOR ANALYZING TRACE AMOUNT OF ELEMENT IN ALLOY

摘要

PROBLEM TO BE SOLVED: To provide the analysis method, which can accurately obtain the amount of the trace amount of element in alloy. SOLUTION: The amount of the trace amount of the element in alloy, which is to be measured, is measured by an emission spectroscopic analysis method. That is, the calibration curve is read out, the large amount of element affecting the trace amount of the element is measured by fluorescent X-ray analysis method and the measured value of the minute amount of the sensor, which is measured by this emission spectroscopic analysis method, is corrected based on the value measured by the fluorescent X-ray analysis method.
