Abstract
An XRF system, preferably handheld, includes an X-ray source for directing X-rays to a sample, a detector responsive to X-rays emitted by the sample, and a filter assembly with multiple filter materials located between the X-ray source and the detector. An analyzer is responsive to detector and is configured to analyze the intensities of X-rays irradiated by the sample at one power setting and to choose a filter material which suppresses certain intensities with respect to other intensities. A device, controlled by the analyzer, automatically moves the filter assembly to the chosen filter material and then the analyzer increases the power setting to analyze certain non-suppressed intensities.
