Installation for treating samples continuously by separation on a stationary phase under forced flow

An installation for treating samples by chromatographic separation, the installation being characterized in that comprises:

• means for feeding a moving phase (1, 2, 4) at a selected flow rate and/or a selected limiting pressure;
• supply means (14) arranged to deliver a multiplicity of samples separately;
• a multiplicity of injector means (10-i) each comprising at least a first inlet (11-i) suitable for receiving a sample delivered by the supply means (14), a second inlet (8-i) connected to the feed means, and at least one outlet (13-i) arranged to deliver the moving phase and/or the sample;
• at least one stationary phase (3) defining at least a multiplicity of sample treatment channels (12-i) each starting at a first selected location (19-i) and each opening out at a second selected location (20-i);
• and
• at least one chamber (17) arranged to house said stationary phase (3) and comprising:
• i) external pressurizing means suitable for applying an external pressure of selected intensity on one face of the stationary phase;
• ii) a multiplicity of inlets each connected to the outlet (13-i) of a respective injector means (10-i) in such a manner as to deliver the moving phase and/or said samples to different first locations (19-i);
• and iii) at least a first multiplicity of outlets (18-i) for discharging the multiplicity of samples treated in the channels (12-i) and reaching the various second locations.
