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).
