Fractionating apparatus having a plurality of sample elution system (S1 - S8) in which a nozzle (N) movable in the direction of the row of fractionation vessels (4, 4, ---) arranged in a matrix is disposes to each of the sample elution system (S1 - S8) and kept standing-by just above an empty fractionation vessel (4), a valve (30) is operated when elution of sample ingredients is detected by photosensor (PD1 - PD8) to drop the sample ingredients to the fractionation vessel (4, 4, ---) and the nozzle is moved after dropping the sample ingredient by a required amount, and in which the nozzle (N) and the valve (30) can be operated individually on every sample elution systems at different timings respectively such that the eluate can be dropped at different timing on every sample elution systems.
