Abstract: The present invention relates to the regeneration of adsorbent matrices that are used for the purification of substances from aqueous liquid samples derived from biological material. The method is adapted to adsorbent matrices that are sensitive to hydrolysis either because of a sensitive base matrix or a sensitive ligand including also a sensitive spacer and is characterized in contacting at least one regeneration solution with the adsorbent matrix which comprises an organic solvent which is water-miscible and has a pH value ?4, preferably ?3 (acid solution) or ?10 but <13 (alkaline solution).

Abstract: An inlet device for a reactor vessel (5) intended for a separation method comprising retaining a substance on a separation medium from a liquid passing through the reactor vessel (5) which contains the separation medium. The device comprises (a) a distributor block (7) enabling a liquid flow to pass through the block into the reactor vessel (5), (b) an inlet block (3), (c) a distribution chamber (1) defined by a space between the distributor block (7) and the outlet side (11) of the inlet block (3), (d) at least one conduit (I; 13a,13b . . . ) passing through the inlet block (3) from the inlet side (10) to the outlet side (11) of said inlet block (3) and ending in the distribution chamber (1), said at least one conduit being able to distribute liquid into the distribution chamber (1), (e) a gross liquid flow direction going perpendicular to the plane of the interface between the distribution block (7) and the distribution chamber (1).
