Abstract
A system for providing a solvent or reagent to a liquid chromatography system comprises: a valve comprising a common port and a plurality of other ports, configurable such that the common port may be fluidically coupled to any one of the other ports; a pump fluidically coupled to the common port of the valve; a plug configured to block flow through a first one of said other ports of the valve; a container containing the solvent or reagent, said container fluidically coupled to a second one of said other ports of the valve; a fluid tubing line having a known resistance to fluid flow fluidically coupled to a third one of said other ports of the valve; and a pressure gauge configured to measure fluid pressure within the pump, wherein the solvent or reagent is provided to the liquid chromatography system by a fourth one of the other ports.
