Abstract
From an analysis probe to be analyzed, impurities such as proteins or solid matter are separated from the analytes to be analyzed by way of dialysis. An analysis solution containing the analytes is separated from an acceptor solution by a membrane of a dialysis cell. The membrane is chosen such that the analytes diffuse from the analysis solution through the membrane into the acceptor solution. In order to maintain as high as possible concentration of analytes in the acceptor solution, the analysis solution is constantly renewed. The acceptor solution remains stationary in an acceptor chamber until the concentration of analytes in the acceptor solution has reached a predetermined value, for example 95%.
