Abstract

An online sample manager of a liquid chromatography system includes a fluidic tee having a first inlet port, a second inlet port, and an outlet port. A diluent pump moves diluent from a diluent source to the first inlet port of the fluidic tee. A valve has a fluidic intake port connected to a process source for acquiring a process sample therefrom. A pumping system moves the acquired process sample from the valve into the second inlet port of the fluidic tee where the process sample merges with the diluent arriving at the first inlet port to produce a diluted process sample that flows out from the outlet port of the fluidic tee.
