ABSTRACT:
The present invention is concerned with a process and apparatus for generating back pressure in a liquid chromatography system, in that the eluent after having passed through the detector cell is caused to pass through a valve, said valve generating a back pressure and having for this purpose a passage (A-B) which is formed, at an interface between two bodies (20, 24), only when a sufficiently high liquid pressure has been attained, at least one of said bodies being a body of an elastic material.
