Total reflection X-ray fluorescence analysis of highly mineralized water samples using relative intensities and scattered radiation

2020 atomic spectrometry update – a review of advances in X-ray fluorescence spectrometry and its special applications

“…In a fundamental parameter approach , Garmay et al 57 used the dependence of the Rayleigh and Compton scattering intensity ratios on the low-mass matrix content to determine light-element concentrations in mineral water. Rayleigh scattering intensities were used for the sample mass determination.…”

Determination of Sr to Ca ratio in solid carbonate, fluoride, and nitrate samples using the fundamental parameters of EDXRF: experimental and empirical evaluation of non-destructive assays in light matrices

“…These reports described the use of intensity ratios and scattered radiation. [22][23][24][25][26][27] Generally, analytical chemists are required to provide compositional information at zero or low cost of sample quantities. Most of these end-users prefer non-destructive swi techniques over destructive routes.…”

Summary of ISO standard 20289: Total reflection X‐ray fluorescence analysis of water

“…It was then further exploited in other application fields where there was a demand for measuring low mass volumes where the sample was then deposited onto X‐ray reflective surfaces. Material surface analysis remains at the heart of TXRF, but more recently, the availability of commercial benchtop TXRF instrumentation has increased the use of TXRF for analysing many different types of samples: Nowadays, TXRF is used widely to perform elemental analysis of water, soils, bio‐monitors, food, and biological matrices . In these contexts, the community has so far been focused on developing specific sample preparation protocols to ensure the analytical performance of the method .…”
