ABSTRACT:
A device for determining at least one petroleum characteristic of a geologic sediment sample placed in a boat, said device including a first heater heating said sample in a non-oxidizing atmosphere, a measuring component determining hydrocarbon-containing products released after feeding the sample into said first heater, a second subsequent heater heating said sample in an oxidizing atmosphere, a measuring component determining the amount of CO.sub.2 contained in effluents discharged from the two heaters, said CO.sub.2 measuring means include a cell for measuring continuously CO.sub.2 throughout heating of the first and second heaters and a measuring component determining the amount of CO contained in the effluents discharged from the two heaters, and thereby allowing determination of said petroleum characteristic.
