Abstract

An analytical device, including: a processing system for treating a liquid sample and for supplying the treated liquid sample to a measuring cell, to the liquid sample; a measuring transducer for registering a measured value of the treated liquid sample variable; a control unit to control the processing system; and an evaluating unit for determining the measured variable based on the measured value registered by the measuring transducer. The analytical device includes at least one first supply container containing a first reagent component, at least one second supply container containing a second reagent component and a mixing apparatus, for mixing a predetermined amount of the first reagent component contained in the first supply container with a predetermined amount of the second reagent component to form a predetermined amount of the reagent.
