New generation amperometric gas sensors

测量化学物质的需求无处不在。该项目提出了全新的概念，以改变电化学气体传感器的性能——世界市场估计每年有15亿个，应用于环境监测、汽车排放控制、工业安全和医疗。咨询公司Frost and Sullivan表示，“终端用户的普遍需求是体积更小、价格更便宜、功能更多功能的仪器”。电化学方法在低成本、小体积、低功耗的传感器中得到了广泛的应用。这种传感器也非常适用于需要可靠的远程监控的地方。应用的说明性例子包括烟雾报警器中的一氧化碳探测器、水处理中使用的氧气传感器、氯传感器、环境监测中使用的硫化氢和二氧化氮传感器以及大气传感中使用的臭氧传感器。目前的电化学传感器是基于早在1956年就开发出来的设计！与气体传感器制造商和用户的讨论使申请人确信迫切需要新一代安培传感器。本提案中提出的工作目的是通过利用完全由离子（带电粒子）组成的液体的特殊性质与尽可能小尺寸的电极相结合来提供这些新型传感器，以制造响应速度更快的传感器，寿命更长的传感器，不需要校准的传感器以及易于在低温和高温下使用的传感器。

The need for measurements of chemical is ubiquitous. This project proposes entirely new concepts to transform the performance of electrochemical gas sensors - for which the world market is estimated at 1.5 billion annually, with applications in environmental monitoring, automotive emission control, industrial safety and medical treatment.Consultants Frost and Sullivan say 'a general demand from the end user is for an instrument that is smaler in size, cheaper in price, and veratile in functionality'. Electrochemical methods are widely used especially where low cost, compact and low power sensors are needed. Such sensors are also highly suitable where reliable, remote monitoring is needed. Illustrative examples of applications include CO detectors in smoke alarms, oxygen sensors, chlorine sensors used in water treatment, hydrogen sulphide and nitrogen dioxide sensors used in environmental monitoring and ozone sensors used in atmospheric sensing.Current electorchemical sensors were based on a design developed as long ago as 1956! Discussions with manufacturers and users of gas sensors have convinced the applicants of an urgent need for a new generation of amperometric sensors. It is the purpose of the work suggested in this proposal to provide these new sensors by using the special properties of liquids composed entirely of ions (charged particles) in combination with electrodes of the tiniest size possible to make much faster respondig sensors, much longer lived sensors, sensors which have no need for calibration and sensors which can be easily used at low and high temperatures.
