ABSTRACT:
A multi-column countercurrent chromatograph utilizes a single reel with a plurality of columns, typically preparative, semi-preparative and analytical types helically wound around a common central axis in various combinations. The multi-coil column may consist of an inner preparative coil in the range of 215 ml; a 75 ml semi-preparative intermediate coil and 15 ml mini analytical coil for rotation around a central axis. The mini coil is particularly useful for preliminary tests of solvent systems or for separations on a few milligrams of sample. The intermediate coil is useful for preparative separations of larger samples in less than an hour. By connecting the intermediate and larger coils in a series arrangement the resolution obtained will be double that achieved with the intermediate coil alone. Separations can be repeatedly injected without loss of the stationary phase. Individual coils may be used without the need for rebalancing the instrument.
