摘要

Device and method for measuring the content of at least one cosntituinte gas contained in a gaseous sample from a fluid and kit for analyzing at least one cosntituinte gas contained in a fluid of petru00e0leo.The present invention relates to a device which comprises a means (111) to form a gas flow from the sample, and a means (121) for separation by means of selective retention of each constituent gas.It comprises a means (113) for combustion of the gas stream to form a gaseous residue from each constituent, and a means (115) for quantifying the content of each constituent to be analyzed in the gas stream.The means of quantification (115) comprises a cell optical measurement (127) which is connected to the middle of combustion (113), and a means (161) for introducing the laser optical signal incident on the ballot (127).The means of quantification (115) comprises also means (133) to measure the optical signal transmitted from from the interaction between the optical signal and each residual gas on the ballot (127), and means (125) to calculate the content based on the optical signal transmitted.
