Total organic carbon in an aqueous or gaseous sample is measured by admitting the sample and an oxidant gas to a cell (10) transparent to plasma, establishing a relatively low energy plasma in the cell, and measuring the CO2 thus produced using FTIR, NDIR, or conductivity-based techniques.
Selon l'invention, le carbone organique total est mesuré dans un échantillon aqueux ou gazeux par introduction de l'échantillon et d'un gaz oxydant dans une cellule (10) perméable au plasma, établissement d'une énergie plasma relativement faible dans la cellule, et mesure du CO2 ainsi produit au moyen de techniques à infrarouge à transformation de Fourier, de techniques à infrarouge non diffuseur, et de techniques fondées sur la conductivité.
