Abstract
A fraction collecting device for a liquid chromatograph has a splitter disposed downstream to a chromatographic column and serving to split the flow from the column into two flow routes individually connected to a mass analyzer serving as a detector and a fraction collector. A plurality of pipes each having a different flow resistance and being connected in parallel with respect to one other are inserted in either of these two flow routes. A control unit serves to select one of these pipes according to inputted parameters indicating the conditions of liquid chromatography to be carried out and controls valves so as to connect this selected one of the pipes to the column through the splitter.
