Abstract
The measuring liquid in analytical optical devices frequently has to be treated prior to the measurement. A device suitable for this purpose is based on an optical cuvette (cell) filled with a suitable reaction solution. The sample liquid is dispensed into the reaction solution with the aid of a capillary. Normally, all the reactants for the reaction are contained in the reaction solution along with the sample liquid. In the case of the device described here, however, some of the reactants are only introduced into the reaction solution using the dispensing capillary. For this purpose, the dispensing capillary, or independently thereof an additional capillary, is filled with the reactant in the solid phase. When the sample liquid and the reactant are mixed with the reaction solution in the capillary, a chemical reaction sets in which results in a characteristic change in the optical absorption. This change serves as a basis for a photometric measurement.
