Abstract

A liquid chromatographic system includes columns, column mounting fixtures to which the columns are mounted, a detector, a collector, a controller and a plurality of RFIDs. A first RFID communicates with the controller and cooperating RFIDs mounted to other components provide information such as the history of components, parameters and the like. They also receive information from sensors relating to the operation of the liquid chromatograph, store the information and transmit it. Moreover, the RFIDs may substitute for hard wiring in many applications and may enable a central computer to control several liquid chromatographic system.
