摘要：

We have applied CVD (chemical vapor deposition) diamond chemical sensor to detect benzene and toluene, volatile organic compounds, possible indication of the existence of environmental hazardous and petroleum in soil/subsoil. Steady-state and transient response of the sensor for both gases have been extensively studied. These studies have shown that the sensor shows a large sensitivity, fast response, high selectivity, large dynamic range, repeatable/reproducible response for the detection of benzene and toluene gases. Activation energy analysis of the sensor for both gases resulted very small values, confirming fast response and high selectivity.
