ABSTRACT:
An x-ray fluorescent analyzer and method for analyzing a sample, including an x-ray beam generator, which generates an x-ray beam incident at a spot on the sample, and creates a plurality of fluorescent x-ray photons. There are a plurality of semiconducting detectors arrayed around the spot so as to capture the fluorescent x-ray photons and in response produce a plurality of electrical pulses suitable for analysis of the sample.
