摘要：

Modelling consists of considering the response and recovery times of a sensor to the target chemical species, as the sum of an 'intrinsic' response/recovery time, independent of the experimental conditions, and of an 'extrinsic' one, linked to the volume of the measurement cell and to the fluid flow. The experimental response/recovery times being almost always dominated by the extrinsic part, a dissymmetry between the response and recovery signals is observed for sensors whose response is not linear with the concentration of the target chemical species.
