Abstract
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.
