ABSTRACT:
The determination of concentration-dependent parameters in a series of measurements, in particular for the determination of dose-effect correlations, the solutions to be developed are each contained in chambers positioned on a round tray in radial symmetrically arrangement. The respective chamber just to be determined is moved underneath the measuring device via a gyratory movement of a round tray controlled by a computer and the vertical disk between the measuring device at the chamber to be measured is also lowered by computerized control so far until the measuring device dives into the solution in the chamber. The device to realize the process comprises a horizontally rotatable round tray as well as a lifting device wherewith either the total round tray including all chambers positioned thereupon can be vertically moved or only that chamber being immediately positioned underneath the measuring device. The measuring device is composed of a measuring cell comprising a suction tube in which the solution to be measured is sucked and a measuring system projecting into said tube. In particular, the process and the device are suited to measure series of concentrations where a reactant, in particular a bioindicator, constantly loses activity in a run of a series of measurements.
