PCT No. PCT/NO91/00116 Sec. 371 Date Apr. 21, 1993 Sec. 102(e) Date Apr. 21, 1993 PCT Filed Sep. 13, 1991 PCT Pub. No. WO92/05420 PCT Pub. Date Apr. 2, 1992.In order to allow verification of the purity of a fluid sample from a pressurized fluid system, a sampling assembly includes a pressure chamber adapted to removably receive a sampling container. An inlet in the pressure chamber of the sampling assembly is connected to a bleed point of the pressurized fluid system of which the fluid is to be sampled, and the fluid in the system is caused to flow for a predetermined time interval through the sampling container in the pressure chamber. An outlet of the sampling assembly is connected to a return point of the fluid system. When the sampling assembly is disconnected from the fluid system, the pressure in the pressure chamber is released and the sampling container now containing a representative sample of the fluid in the system may be removed from the sampling assembly for analysis of its contents.
