摘要
The current invention relates to an apparatus for performing a centrifugal field-flow fractionation. In particular, in the apparatus according to the invention, radial rotary shaft seals (36a/b) are used for sealing the rotating parts of the shaft (61) for carrying out the centrifugal field-flow fractionation and the stationary parts. Furthermore, a separate line is introduced for reducing the pressure differential across these seals. In such way, the driving force driving sample fluid across the seals is reduced, thereby reducing leakage.
