Analysevorrichtung und Analyseverfahren

摘要

An analysis apparatus and an analysis method for the continuous determination of a species in a fluid is disclosed. For that purpose at least one reagent (R1, R2) reacting with the species is added to the fluid (T) in order to produce a reaction product dependent on the concentration of the species. The reaction product is evaluated in a detector device (9, 10). It is desirable to be able to carry out such continuous analyses quickly and reliably. To that end, at a first time after addition of the reagent (R1, R2) the reaction product is determined. A further determination is effected later at a different time. From the difference in the signals obtained with the findings, conclusions are drawn about the concentration of the species in the fluid.
