Abstract: A centrifugal liquid chromatograph, in which, in place of a prior art separating part in a liquid chromatograph, which portion is composed of a separating column and a feed pump, a pair of upper and lower horizontal discs are arranged vertically in spaced relation to each other, so that a separating medium may be filled in the gap defined therebetween, and the pair of discs are rotated, while a solvent as a mobile phase is being introduced through a central port provided in the upper disc into a space defined between the aforesaid pair of discs, whereby the mobile phase may make ingress into a stationary phase due to a centrifugal force, thereby achieving rapid separation of components from a sample, thus dispensing with a feed pump.
