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 RSq = 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
