摘要:
Exemplary embodiments integrate a tee or valve into an outlet end fitting of a liquid chromatography column. The tee or valve is suitable for providing additional fluidic flow paths to ports of the end fitting and eliminates the need for post-column fluidic conduits connecting to tees or valves to insert fluidic inputs or divert flow to outputs. This integration decreases the distance that eluent from the liquid chromatography column has to travel to reach a detector relative to systems that use external tees or valves while providing tee/valve functionality and reducing the fluidic volume post-column. As a result, the exemplary embodiments help decrease sample dispersion.
