Ion Selective Electrode (ISE) sensors are used to detect ionic concentration in aqueous solutions. Through discussions with several ISE sensor users and manufacturers, we have confirmed a fundamental issue with the ISE sensors currently on the market – electrode drift – which severely degrades the sensor’s operational performance and utility as a smart sensor. In-situ ISE sensors have enormous potential across many industries (everything from environmental monitoring to medical/pharmaceutical controls), but the need for calibration to account for drift severely limits use of in-situ ISE sensors. ANB have identified an opportunity to investigate whether part of its novel electrochemical sensor platform can be used to address the issue of drift in ISE’s, in-situ, enabling the vast potential of the sensors to be realised in smart solutions. To address the issue of drift, ANB will utilise a novel means of verifying the electrochemical potential/performance of the reference electrode through the introduction of an additional voltammetric electrochemical measurement. The overall objective of this project is to research, develop and produce at least 5 modified laboratory scale prototype pH sensors utilising the novel self-calibration system over prolonged periods (up to 12 months).

离子选择性电极（伊势）传感器用于检测水溶液中的离子浓度。通过与几家伊势传感器用户和制造商的讨论，我们确认了目前市场上伊势传感器的一个基本问题-电极漂移-这严重降低了传感器作为智能传感器的操作性能和实用性。原位伊势传感器在许多行业（从环境监测到医疗/制药控制）中具有巨大的潜力，但需要校准以解决漂移严重限制了原位伊势传感器的使用。ANB已经确定了一个机会，可以调查其新型电化学传感器平台的一部分是否可以用于解决伊势的原位漂移问题，从而使传感器的巨大潜力在智能解决方案中得以实现。为了解决漂移问题，ANB将利用一种新的方法，通过引入额外的伏安电化学测量来验证参比电极的电化学电势/性能。该项目的总体目标是研究，开发和生产至少5个改进的实验室规模的原型pH传感器，利用新的自校准系统在较长的时间内（长达12个月）。
