TXRF Spectrometers

Total reflection X-ray fluorescence spectroscopy (TXRF) is a powerful analytical technique used for the elemental analysis of samples with very low concentrations of trace elements. In TXRF, a primary X-ray beam is directed onto a sample at a very shallow angle, causing total reflection at the sample surface. This results in an X-ray standing wave within a thin layer of the sample, maximizing the interaction between the X-rays and the sample material. The fluorescence emitted by the sample in response to this excitation is then detected and analyzed to determine the elemental composition and concentration. TXRF is particularly advantageous for analyzing liquid samples or very small sample amounts, as it offers high sensitivity, excellent reproducibility, and low detection limits, making it an invaluable tool in fields such as environmental monitoring, nanotechnology, and semiconductor analysis.
