PHASE INVERTER CIRCUIT: for auto-differential Potentiometry

This differential potentiometric technique is based upon the invention of a new simple electronic RC filter circuit capable of yielding analytical results of high accuracy and precision in addition to having the obvious advantages of very low cost and ease of operation over the earlier conventional and complicated differentiator circuits. The technique has the potential of application to other types of potentiometric estimations such as compleximetry and redox titrimetry.
