In Situ Recalibration of Ion Selective Electrodes

Wadhawan, Jay; Lawrence, Nathan

Abstract

Reference electrode drift resulting from the exchange of ions at the solution/reference electrode chamber interface is the number one reason why ion selective electrodes and pH sensors in particular require recalibration, costing companies up to 70 % of the total lifetime cost of a pH probe. In this work, a novel and innovative methodology is proposed in which the reference potential is tracked, allowing for in-situ recalibration of the sensor without the need for end-user intervention.
