Abstract:
A high-throughput parallel liquid chromatography system connectable to a detector, the system comprising:at least one pump for introducing a carrier into the system;at least two parallel columns;an actuatable, multipositional first valve having a plurality of ports with each port thereof in fluid communication with the at least one pump and with each port being dedicated to one of the at least two columns;an actuatable, multipositional second valve having a plurality of ports with each port thereof being dedicated to and in fluid communication with one of the at least two columns and the like dedicated port of the first valve;an actuatable, multipositional diverter valve operably connectable to the detector and having a plurality of ports with each port thereof being dedicated to and in fluid communication with one of the at least two columns and the like dedicated ports of the first and second valves; andan injector disposed in selectable fluid communication between the respective ports of first and second valves for introducing samples to the carrier, whereby upon selection of one of the at least two columns, the first, second, and diverter valves actuated to position the respective dedicated ports in fluid communication with one another through the injector so that the sample received by the injector is deliverable to the detector.
