Title:
METHOD AND APPARATUS FOR QUANTIFYING ELEMENT
Document Type and Number:
Japanese Patent JP2000155101
Kind Code:
A
Abstract:
To selectively and inexpensively determine specific elements contained in a sheet-like matter per unit area with high accuracy.
This method for determining specific elements contained in a sheet-like matter includes a process for irradiating the sheet-like matter with X-rays in a region on the high-energy side of the X-ray absorbtion edge related to the specific elements, a process for measuring the incident intensity (I0) and transmitted intensity (It) of X-rays transmitted through the sheet-like matter to calculate the absorbance of the X-rays, with respect to the sheet-like matter according to the formula and a process for calculating the amt. of the specific element contained in the sheet-like matter based on the calculated absorbance.
