Analytical testing of the SRXRF experimental station

For the purpose of analytical testing of the experimental SRXRF station at the VEPP-3 SR source together with the methods applied for spectrum processing, an elemental analysis of a set of objects of different nature was carried out for different primary excitation energies in the range from 15 to 45 keV. There were measured the reference samples of geological, soil, marine products, blood and hair as well as synthetic thin films containing compositions from the pair of chemical elements. The mass of the samples was varied from 30 mg to several tens of micrograms. The data obtained (detection limits and reproducibility) at the different excitation energies for the same set of samples and different elements are discussed.
