Abstract: An installation for separating components, in particular by high-pressure liquid chromatography along a plurality of channels in parallel, the outlets from the channels being connected via controlled selective connection means to the inlets of parallel temporary storage means whose outlets are connected via controlled selective connection means to ducts for depositing in collector means or in disposal means.

Abstract: An installation for treating samples by chromatographic separation comprises: i) means (1, 2, 4) for feeding moving phase, means (14) for supplying samples, and a multiplicity of injector means (10-i), each comprising a first inlet (11-i) for receiving a sample, a second inlet (8-i) connected to the feed means, and an outlet (13-i) for delivering the moving phase and/or the sample; ii) a stationary phase (3) defining a multiplicity of sample treatment channels (12-i), each starting at a first selected location (19-i) and terminating at a second selected location (20-i); and iii) a chamber (17) housing the stationary phase (3) and including pressurizing means for applying an external pressure to one face of the stationary phase, a multiplicity of inlets, each connected to the outlet (13-i) of an injector (10-i) to deliver the moving phase and/or the samples to the first locations (19-i), and a multiplicity of outlets (18-i) for discharging the multiplicity of samples treated in the channels (12-i) that have re

Abstract: Apparatus for separating the components of a sample by OPLC type chromatography using liquid under pressure, the apparatus comprises a stationary phase forming one or more sample treatment paths and means for feeding moving phase to one end of the stationary phase, with means at the opposite end of the stationary phase for collecting moving phase, means for injecting moving phase also being provided at the sides of the stationary phase in order to eliminate edge effects in the fronts of sample components and in order to separate treatment paths from one another.
