Fluorescent X-ray analysis method and fluorescent X-ray analysis apparatus |
摘要 |
The concentration(s) of element(s) contained in an unknown sample is measured without necessity of judging the sample relying on a human's eye and obtaining information from a supplier of the sample previously. The concentration(s) of trace element(s) such as Cd, Pb and Hg contained in parts for electronic or electric equipment is determined by (1) irradiating the sample with an X-ray so as to identify whether the type of the sample is a nonmetal-based material or a metal-based material; (2) selecting measuring conditions for a fluorescent X-ray analysis depending on the identified type of the sample; and (3) measuring the concentration(s) of one or more element(s) contained in the sample by the fluorescent X-ray analysis according to the selected measuring conditions.
