Beschreibung
Zusammenfassung:	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 line 1 thereof to a bypass line 2 . By restoring circulation of the emulsion in main line 1 , an emulsion sample still present in bypass line 2 is 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.
