Abstract: A coulometric titrator for determining, at high accuracy and without time delay problems, small amounts of a specific ion in a solution by the addition of a reactive ion. A sensor provides a signal voltage representing the logarithm of the specific ion concentration to a differential amplifier which also receives as an input a signal from a reference electrode. The differential amplifier produces an error signal applied to a comparator and referenced therein to a certain reference voltage representing a desirable range of rates of change of the error output voltage. The comparator provides a sensor signal voltage representing the difference between the error signal and reference voltage. This sensor signal voltage is applied to an antilogarithm converter which produces an output signal that is proportional to the antilogarithm of the sensor signal voltage.
