Self-calibrating platform for all Ion Selective Electrodes facilitating in-situ smart monitoring.

离子选择电极(ISE)传感器用于检测水溶液中的离子浓度。通过与几家ISE传感器用户和制造商的讨论，我们确认了目前市场上的ISE传感器存在的一个根本问题-电极漂移-这严重降低了传感器的运行性能和作为智能传感器的实用性。现场ISE传感器在许多行业(从环境监测到医疗/制药控制)具有巨大的潜力，但需要校准以解决漂移问题，这严重限制了现场ISE传感器的使用。ANB已经找到机会调查其新型电化学传感器平台的一部分是否可以用于就地解决ISE中的漂移问题，从而使传感器的巨大潜力能够在智能解决方案中实现。为了解决漂移的问题，ANB将使用一种新的方法来验证参考电极的电化学电位/性能，方法是引入额外的伏安电化学测量。该项目的总体目标是研究、开发和生产至少5个改装的实验室规模的PH值传感器原型，在较长的时间内(长达12个月)利用新的自校准系统。

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).
