  • Device for ion-exchange chromatography and method of cyclically regenerating a plurality of suppressors of such a device
    Patent number: 6153101
    Abstract: In order to regenerate a plurality of suppressors (6, 6a, 6b) that are inserted alternatingly into a device for ion-exchange chromatography, apart from an analysis branch (9), at least one additional treatment branch (10, 10a) is anticipated, through which a treatment agent (7, 7a) can be fed. The analysis branch (9) and the treatment branch (10, 10a) each possess a gap (34) in which the suppressors (6, 6a, 6b) can be alternatingly inserted. In order to insert a suppressor in a pipework branch, the suppressor is moved relative to the pipework branch until the connection openings (36a, 36b) of the suppressor are aligned with the corresponding pipe openings (35) of the gap of the pipework branch concerned.
