Claim:
1. A device for analyzing at least one hydrocarbon contained in a drilling fluid, comprising: an extractor for continuously extracting gases contained in the drilling fluid, the extractor having an outlet at which the gas stream is sampled, the gas stream containing at least one hydrocarbon to be analyzed and at least one interfering compound; a transport line, connected to the outlet of the extractor to transport the gas stream; an analyzer comprising a detector able to measure the hydrocarbons to be analyzed in the gas stream; and a chemical reactor located between the extractor and the detector and receiving at least part of the gas stream, the chemical reactor being able to carry out a selective catalytic reaction of at least one interfering compound present in the gas stream without any substantial reaction of at least one of the hydrocarbons to be analyzed, wherein the at least one interfering compound comprises ethylene (C2H4), wherein the chemical reactor contains a catalytic system having a catalyst dispersed on a support; wherein the catalyst comprises at least a transition metal, wherein the transition metal comprise at least one of platinum, rhodium or palladium.
