WebThe TXRF working principle is based on the method of total reflection X-ray fluorescence analysis. An aircooled X-ray tube generates an X-ray beam, which is reduced to a narrow energy range by a multi-layer monochromator. The fine beam impinges on a polished sample carrier at a very small angle and is totally reflected. WebWhat is WDXRF and how does it work? The basic concept of all spectrometers is a radiation source, a sample and a detection system. In WDXRF spectrometers, the X-ray tube acting as a source irradiates a sample directly, and the fluorescence coming from the sample is measured with a wavelength dispersive detection system. The characteristic radiation …
