How does TXRF work? - Bruker
网页What is TXRF? The 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.

Total Reflection X-ray Fluorescence - EAG Laboratories
网页Total Reflection X-ray Fluorescence (TXRF) utilizes extremely low-angle X-ray excitation of a polished wafer surface to obtain the concentration of surface metallic contaminants. The incident angle of the X-ray beam (typically 0.05-0.5°) is below the critical angle for the substrate and limits excitation to the outermost surface of the sample ...
科学网—[转载]全反射X荧光（TXRF）分析技术 - 贾志谦的博文
网页2021年4月30日 · 全反射X荧光（TXRF）分析技术，是近年来发展起来的多元素同时分析技术。 TXRF利用X射线全反射技术，将样品在反射体兼样品架上涂成薄层（nm级）进行激发。 由于入射X射线和出射X射线的强度相等，消除了原级X射线在反射体上的相干和不相干散射现象，使散射本底降低了约3-4个数量级，使样品荧光的杂散本底比X荧光能量色散谱仪（EDXRF）本底降低约四个量级，从而大大提高了能量分辨率和灵敏度，避免了XRF测 …
