Carbon and oxygen XRF spectra were studied using a WDXRF (WD X-ray fluorescence) spectrometer S8 TIGER (Bruker AXS, Germany). XRF spectra were obtained from the samples of the calcareous spar (CaCO3) (pure calcium carbonate), the limestones, the graphite, the microcrystalline cellulose, various organic compounds and prepared mixtures on the basis of the calcareous spar with addition of the graphite and the microcrystalline cellulose. The studied samples of the limestones are characterized by high concentrations of calcite (98.5-99%). Main objective of this investigation is to develop WDXRF technique for the determination of C(total) and O(total). Optimal instrumental measuring conditions were selected experimentally for quantitative determination of C(total) and O(total). The calculated values of the ILD (instrumental limit of the detection) vary from 0.0215% for C(total) to 0.0331% for O(total), respectively. The obtained values of the LDM (limit of determination of the XRF method) do not exceed 0.08% for C(total) and O(total). The RSDs (relative standard deviations) values do not exceed 1.0% in all cases.
