In order to allow verification of the purity of a fluid pressure from a pressurized fluid system (S) there is provided a sampling assembly (1) comprising a pres- sure chamber (2) adapted to removably receive a sam- pling container (22). An inlet (12) in the pressure cham- ber (2) of the sampling assembly (1) is connected to a bleed point (A) of the pressurized fluid system of which the fluid is to be controlled, and the fluid in the system is caused to flow for a predetermined time interval through the sampling container (22) in the pressure chamber (2), the outlet (14) of the sampling assembly (1) normally being connected to a return point (B) of the fluid system (S), whereupon the sampling assembly (1) is disconnected from the fluid system (A), the pres- sure in the pressure chamber (2) is released and the sampling container (22) now containing a representa- tive sample of the fluid in the system, may be removed from the sampling assembly for analysing its contents.
