ABSTRACT:
An X-ray analyzer capable of reducing the effects of a shift of peak positions in an energy spectrum resulting from a change in temperature and a lapse of time in an X-ray detector to enable a highly accurate analysis.
A shift of peak positions of X-rays from known positions are detected and a voltage applied to a proportional counter is controlled on the basis of the detected results. In addition, a gain in an amplifier amplifying an output from the X-ray detector may be controlled on the basis of the detected results.
