Abstract:
An automated titration machine, TITRON was designed using a syringe pump and Labview controller. TITRON controlled the syringe pump to provide titrant at two rates: a fast rate of 11.76 + 0.02 ml/hour in the buffer regions and a slow rate of 0.69 ml/hour during the region around the equivalence point, the critical region. A circuit was designed to disconnect the syringe pump from power between the buffer region and the critical region and again before the second buffer region. TITRON also determined the volume and potential at the equivalence point. Human titrations were shown to have the same equivalence point (with 95% confidence) as TITRON, demonstrating the validity of the experimental setup. Then, Excel determination of TIRON equivalence point was found to be the same (with 95% confidence) as TITRON determination of equivalence point, demonstrating the validity of the equivalence point algorithm developed in Labview.
