Thermal analysis combined with mass spectrometry was applied to radiocarbon dating procedures (age determination of carbon-containing
samples). Experiments carried out under an oxygen atmosphere were used to determine carbon content and combustion range of
soil and wood samples. Composition of the shell sample and its decomposition were investigated. The quantification of CO2 formed by the oxidation of carbon was done by the application of pulse thermal analysis. Experiments carried out under an
inert atmosphere determined the combustion range of coal with CuO as an oxygen source. To eliminate a possible source of contamination
in the radiocarbon dating procedures the adsorption of CO2 by CuO was investigated.
