ANNULAR CHROMATOGRAPHY DEVICE

PURPOSE:To provide an annular chromatography device which does not require any space for maintenance and inspections above a packed column main body. CONSTITUTION:The device is provided with a packed column main body having an annular chromatography device substrate 15, cylindrical outer column 1 coupled with the upper surface of the substrate 15, and inner column 2 which is concentrically arranged in the outer column 1 and forms an annular separating agent housing section together with the internal peripheral surface of the column 1. The device is also provided with a chromatography device table 40 which supports the packed column main body, a pair of supporting arms 16 with one ends fixed to the substrate 15, and inclined driving shaft 17 which is nearly horizontally positioned and to which the other ends of the arms 16 are fixed. In addition, a harmonic driving motor 32 which rotates the shaft 17 is also provided. The substrate 15 is removably coupled with the table 40 with bolts 34.
