As a consequence, gradient facilities are not usually fitted to preparative chromatographs. In addition, complex data acquisition and processing systems are not required,althoughprogrammablefractioncollectorsareoften necessary which are usually controlled from the detector output. The layout of a preparative chromatograph is depicted in figure 11.
