Technical Field

Among the numerous analysis devices, some devices such as chemiluminescent gas analyzers have the advantages of high detection sensitivity, high accuracy, etc., but are not used for on-site real-time monitoring due to their large size, and are expensive, and their application is greatly limited beyond the affordability of the general detection users. Other analytical devices, such as semiconductor gas sensors (e.g., sn02, zno, etc.), are relatively sensitive, although operating at temperatures above 300℃in most cases, require heating means, limiting their use in hazardous environments. In contrast, the electrochemical sensor not only can meet the requirements of sensitivity and accuracy in general detection, but also has the advantages of small volume, simple operation, convenient carrying, on-site monitoring, low price and the like, so the electrochemical sensor occupies an important position in various existing gas detection equipment at present.
Due to the influence of the electrochemical detection principle, environmental water vapor has a great influence on the sensor measuring element: not only can deviation be generated on the measurement result, but also the service life of the detection element can be greatly reduced. It is a challenge for sensor design to both effectively measure the concentration of gas in the environment and to prevent the influence of moisture in the environment on the measuring element.
