Determination of suppressor in acid copper baths by smartDT
Tóm tắt
The determination of suppressor with dilution titration (DT) involves numerous additions with standard solution or sample to reach the evaluation ratio. Usually fixed, equidistant addition volumes are used. With smartDT, variable addition volumes are used that are automatically calculated by the software. At the beginning, the volumes are bigger. Towards the evaluation ratio, the addition volume becomes smaller to guarantee a good accuracy of the result. The operator defines the first and the smallest addition volume to be used. All volumes in between are calculated by the software considering the progress of the determination. Using smartDT with intelligent addition volumes, the determination of suppressor can be significantly accelerated with the same or even better accuracy than with the classic DT. The time saving per determination is between 20 and 40%.
