摘要/Abstract

摘要： 利用六西格玛(six sigma)统计工具对电化学硫化氢(H₂S)气体传感器的气体敏感特性进行了研究, 并运用Minitab 软件对测试数据进行了系统分析. 结果显示, 所测电化学气体传感器对H₂S气体响应良好, 灵敏度平均值为0.82 μA/10⁻⁶H₂S. 在H₂S 传感器的量程范围(0∽100×10⁻⁶)内, 传感器的响应输出值与H₂S 气体体积分数呈现良好的线性关系, 相关指数R_Sq=99.9%; 传感器对气体的响应速度较快, 响应时间T₉₀< 20 s. 同时讨论了温度变化对H₂S 传感器灵敏度和响应输出值的影响.

关键词: H₂S, 电化学传感器, 敏感特性, 统计工具

Abstract: The sensitive characteristics of electrochemical H₂S sensor are studied by applying six sigma statistical tools. The Minitab software is used to analyze the experimental data. The results show that the gas sensor has a quick response to H₂S gas, the average sensitivity is 0.82 μA/10⁻⁶H₂S, the gas sensor has a good linear relationship with concentration of H₂S in the measurement range of the sensor, the correlation index R_Sq = 99.9%, and the response time T₉₀< 20 s. The influences of temperature on sensitivity and on the average response value of H₂S sensor are also discussed.

Key words: electrochemical sensor, H₂S, sensitive characteristic, statistical tool
