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.
