Continuous measurements of pH and conductivity yield instantaneous values for the amount of dissolved trace substances as well as the acidity. The synchronous measurement of the two parameters allows quality control of the results and a good estimate of the amount of free acid in the precipitation. Acidity and amounts of trace substances obtained by precipitation correspond closely to the temporal development of the precipitation event. Therefore the concurrent measurement of amount and intensity of precipitation gives insight into the physics of the removal processes. Further analysis of precipitation is possible through the separation of material flowing through the measurement block and material collected in the optional sample bottle.
