A device for performing a post-column derivatization in connection with liquid chromatography includes a separating column, a detector, an eluent withdrawal unit, connected to an outlet of the separating column, that withdraws eluents from the separating column, a reagent supply unit, arranged between the outlet of the separating column and an inlet of the detector, that supplies reagents to the eluents withdrawn from the separating column and a pump that simultaneously pumps eluents from the eluent withdrawal unit and pumps reagents to the reagent supply unit, wherein the pumping of reagents takes place free of pulsations.
