The invention relates to a device and a method for separating substances by liquid chromatography. The aim of the invention is to provide a device and a method by which means substances can be separated by liquid chromatography under pressure and which enable parallel separation and detection of at least several samples. The device should have a compact, economical construction. To this end, the inventive device for separating substances by liquid chromatography under pressure is characterized in that at least several liquid chromatography separating lines ( 17 ) are supplied by a single delivery unit (one or two pumps), said separating lines being arranged so that they run parallel, and in that said separating lines are combined with a sample-loading system ( 5 ) and an injection system ( 18 ) in the sample introduction area and with a multi-channel detector ( 13 ), connected to an evaluation and control unit ( 16 ), in the detection area.
