| Abstract: | An automated conductometric titration system has been designed and investigated. Stepper motor driven burets have been constructed to provide precise delivery of small volumes of titrant. A bipolar pulse conductance instrument of wide dynamic range is briefly reviewed as a tool in conductometric titrations. Several types of titrations have been carried out to investigate the accuracy and reproducibility of this apparatus. The precision for titrant volumes of 40µl is ±0.64% relative standard deviation. |
