The method of total reflection X-ray fluorescence (TXRF) analysis

Fri, 03 Jan 2025 02:00:00 +0100

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 sm...
