Comparison RS200 & RS300

X-Ray fluorescence is one of the most versatile methods to determine element concentrations in a solid sample. The material is exposed to high-energy X-rays that cause each element to emit its own characteristic fluorescent X-ray. The analysis of the results is based on comparisons to standard samples with given chemical composition. Sample preparation has become an increasingly important issue because the detection limit of XRF analyzers has shifted to trace level in the past few years. Moreover, accurate analysis of major light elements is only possible with finely ground, homogeneous samples.
