An improved method is presented for determining the equivalence point in potentiometric titrations. Titration rate and data acquisition are under computer control, and lonselective electrodes are used as Indicators. As the titration proceeds, the potentiometric curve and Gran (antilog) plot are displayed on a CRT. Upon completion of the titration, the operator uses interactive graphic techniques to interrogate the Gran plot and develop an error function. This error function identifies the period during the potentlometrlc titration when the cell output is most nearly Nernstian. Data obtained during the identiiied period are used to estimate the equivalence point. Data are presented together with a discussion of the characteristic features of the error function.

“…The electrode system was immersed in each solution, and the emf reading was recorded and compared with the calibration plot. Alternatively, the standard addition spiking technique 21 was used by measuring the potentials displayed by the test solution before and after the addition of 1.0 ml of a 10 -1 M thiopental solution to 100 ml of ca. 10 -3 M solution.…”

“…Even more compact are the integrated microchemielectronic devices with ion-selective electrodes as detectors. The coated-wire approach (13) and PVC membranes (14,15) are fully compatible with microconduit technology. Multielectrode systems for simultaneous pH and potassium measurement using a common reference electrode have been developed in our laboratory.…”
