DEVICE AND METHOD FOR THE PARALLEL SEPARATION OF SUBSTANCES BY LIQUID CHROMATOGRAPHY

摘要

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 leas t 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 characterised in that at least several liqu id 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-loadi ng 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.
