Leak detection upstream of a mixing point

摘要

A sample separation device (100) for separating a sample, the sample separation device (100) comprising a first fluid conduit (102) for conducting a first fluid, a second fluid conduit (104) for conducting a second fluid, a sample separation unit (106) adapted for separating the sample, a mixing point (108) in fluid communication with and arranged downstream of the first fluid conduit (102) and the second fluid conduit (104) and adapted for mixing the first fluid with the second fluid to supply the mixed fluid composition towards the sample separation unit (106) for separation of the sample comprised in the fluid composition, and a leak detection unit (110) adapted for detecting a leak upstream of or at the mixing point (108).
