The present invention relates to a device for separating an effluent comprising phases of different density and conductivity, the device comprising a pair of electrodes (), means () for introducing the effluent between said electrodes, means intended for separation () and discharge () of said separated phases. The separation means comprise at least one centrifugation element including a helical channel () in which the effluent is centrifuged after passing between the electrodes. An opening extends over the entire periphery of said centrifuged effluent so as to discharge part of the centrifuged effluent. The discharge means further comprise sealing means for limiting discharge of the less dense phase through said opening.

The present invention is intended to take a sample of an emulsion circulating in a line. The emulsion is momentarily diverted from the main circulation linethereof to a bypass line. By restoring circulation of the emulsion in main line, an emulsion sample still present in bypass lineis confined under pressure. The emulsion sample is then stabilized according to a well-known method. Since the size and the distribution of the drops no longer evolve with time, the sample can be observed and analyzed after sampling. The invention more particularly applies to the field of petroleum industry and it is notably intended to take a sample of a petroleum effluent in form of an emulsion at wellheads.
