Abstract
The present disclosure is related to an analytical system comprising a liquid chromatographic (LC) system comprising a plurality of fluidic streams alternately connectable to a common detector via a stream-selection valve connected to the detector via a valve-to-detector conduit. The analytical system further comprises a wash pump fluidically connected to the stream-selection valve and configured to connect to the valve-to-detector conduit between two consecutive fluidic streams in order to wash liquid from a previous fluidic stream out of the valve-to-detector conduit before liquid from a subsequent fluidic stream enters the valve-to-detector conduit. An analytical method comprising switching between the fluidic streams and washing in between is also disclosed.
