Abstract

A liquid chromatographic (LC) system is herein disclosed, the LC system comprising at least one fluidic stream comprising at least one HPLC column, a downstream valve connected to the at least one fluidic stream and connectable to a detector via a valve-to-detector conduit, wherein the at least one fluidic stream is connectable to the valve-to-detector conduit via the downstream valve, and where the LC system further comprises a downstream pump fluidically connected to the downstream valve and connectable to the at least one fluidic stream via the downstream valve in order to backflush and thereby clean the at least one HPLC column. A respective automated LC method is herein also disclosed.
