Centrifugal liquid chromatograph

A centrifugal liquid chromatograph comprising;

• separating means consisting of a pair of upper and lower horizontal discs which are vertically arranged in spaced-apart relationship with respect to each other, and a porous spacer disposed between said pair of discs along the circumference thereof, said separating means having a space defined between said pair of discs and filled with a separating medium, said upper disc having a central inlet port, through which a sample and a developer are to be fed to said separating means, said porous spacer consisting of a rigid core wire having a ring shape and a coil of rigid wire of a considerably small gauge wound around said rigid core wire in a spiral form at substantially a constant pitch and a tape of porous material closely adhered to the coil of rigid wire of considerably small gauge in a manner to fill the respective gaps between the adjoining wires of a considerably small gauge;
• a drive unit for rotating said separating means in a manner to permit adjustment of the r.p.m. thereof, and for forcing components separated from a sample towards the circumferential portion of said separating means due to centrifugal force;
• and
• detecting means for receiving the sample forced out from the outer circumferential portion of said separating means and detecting components separated from the sample.
