A method and apparatus (1) is disclosed for separating, by means of a probe, a partial flow from a flow of gases coming from an exhaust pipe (8) of, for instance, an engine such as a diesel engine for a vehicle (9), the exhaust pipe being connected, by means of a connectable conduit (4)which can be sealed, to a chamber formed by a number of walls, which chamber is surrounded by a housing (2) and communicates, by at least one wall passage, with a space defined between the housing and the chamber walls in which, by extraction means (3, 5, 6) and via optionally suction openings which can be closed, an extraction flow to a remote location is generated, to which extraction flow the flow of gases coming from the exhaust pipe and fed to the chamber via the conduit, and the partial flow separated via the probe, are added.
