ABSTRACT:
There is disclosed a column for use in a continuous particle separation apparatus utilizing a centrifugal field. The column comprises a column base constituting an outer frame, a spacer having a cutout portion at its center, an intermediate ring having a slot and a variable diameter, and a top ring mounted inside the intermediate ring. The intermediate ring has an inlet port and an outlet port for introducing and discharging fluid near the slot. The intermediate ring has an inclined inner surface. The top ring has an inclined outer surface which is pressed against the inclined inner surface of the intermediate ring to expand the intermediate ring. Thus, the spacer is pressed against the base. A separation channel is formed between the inner wall of the base and the intermediate ring within the cutout portion of the spacer.
