ABSTRACT:
A high pressure liquid chromatograph system which includes a plurality of columns and a plurality of solvent containers (reservoirs) and which are selectable by use of a select or subsystem to permit the desired measurement (analysis) to be made by the system. With this system one may conveniently use a particular solvent system and a particular column to obtain a recording which is believed to be the most definitive by the user. Selection may conveniently be made by the user or by a microprocessor in accordance with predetermined program so that a completely automated overnight analysis of large numbers of different samples may be made.
