Controlling fluids provided to a chromatographic detector.

摘要

An apparatus and method for controlling carrier fluid and/or support fluid provided to a chromatographic detector (30) is disclosed. The chromatographic column (18) is provided with means which measure a physicochemical property of the fluid (e.g flowrate) and signal control means (40) upstream of the detector which modify the physicochemical property (e.g by providing an amount of make-up fluid.
