Abstract:
An X-ray analyzer comprising an electron beam source for generating an electron beam, an electron beam converging section for converging said electron beam onto a specimen, and an X-ray detecting section for detecting a characteristic X-ray generated from said specimen upon irradiation with said electron beam;said X-ray analyzer further comprising: an absorption current measuring section for measuring an absorption current value from said specimen and measuring an absorption current value from a reference sample disposed so as to be interchangeable with said specimen; a proportionality factor calculating section for calculating a value of ratio A between respective absorption current values in said specimen and reference sample; and a reference sample absorption current calculating section for calculating, when said specimen is finally measured, an absorption current value of said reference sample at each measuring time by multiplying each measured absorption current value of said specimen by the value of ratio A determined by said proportionality factor calculating section.
