ABSTRACT:
This application discloses a liquid chromatography system which can be operated in a batch or a continuous mode. The system consists of the chromatographic column, a reaction column wherein the substances previously separated are reacted to form a readily detected compound and a loop to recycle the mobile phase for reuse. A prime feature of this system is having the mobile phase contain a reactant which upon reaction with an unknown produces a readily detectable compound. This system is very suitable for plant quality control operations and is of considerable value in analyzing compounds having primary amine functionality.
