Patent ID: 8448495

Claim:
A quantifying device for quantifying a content of at least one gaseous constituent contained in a gaseous sample from a fluid, said device comprising: a formation unit for forming a gaseous flow from the gaseous sample, said formation unit including a separation device for separation by selective retention of each gaseous constituent to be analyzed; an oven for combustion of the gaseous flow, said oven being connected to said separation device to successively form a gaseous residue from each constituent; and a quantification unit for quantifying the content of each constituent to be analyzed in the gaseous residue, said quantification unit including: an optical measurement cell including a confinement chamber for receiving the gaseous residue from said oven, and a transportation unit for transporting the gaseous residue from said oven to said confinement chamber; a guide mechanism for guiding a laser incident optical signal into said optical measurement cell; a sensor for measuring a transmitted optical signal resulting from an interaction between the laser incident optical signal introduced into said optical measurement cell and the gaseous residue received within said optical measurement cell; and a calculation unit for calculating the content of the gaseous residue based on the transmitted optical signal.
