http://cais.uga.edu/wp-content/uploads/2024/01/XRF_Background.pdf 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. WebMartina Schmeling (Editor), Diane Eichert (Editor) A Practical Guide to Total Reflection X-ray Fluorescence discusses how a wide range of samples can be analyzed using Total Reflection X-ray Fluorescence (TXRF) to obtain meaningful and accurate results.
