摘要

The invention relates to a dialysis cell (1) for sample preparation for a chemical analysis method, in particular for ion chromatography. The dialysis cell (1) comprises a donor channel (2) and an acceptor channel (3) extending parallel thereto. The donor channel (2) and the acceptor channel (3) are separated from each other by a selectively permeable dialysis membrane (4). In particular, an analyte (5) that is dissolved in a donor solution in the donor channel (2) can enter through the dialysis membrane (4) into the acceptor solution in the acceptor channel (3). The acceptor channel (3) has at least in some sections a volume (V_A) that is smaller than the volume (V_D) of the donor channel (2) extending parallel thereto. Acceptor and donor channels are formed from half-cells (6, 7), between which the dialysis membrane (4) is arranged, wherein the donor channel (2) and the acceptor channel (3) are designed in each case as a recess in a contact surface (8, 8') of one of the half-cells (6, 7) with the dialysis membrane (4).
