Toward membrane-free amperometric gas sensors: a microelectrode array approach.

Abstract:

Room temperature ionic liquids (RTILs) have been applied to a microelectrode array and been demonstrated to form effective, membrane-free amperometric gas sensors. Determining the RTIL [P(6,6,6,14)][FAP] as the most appropriate choice for extended use, the amperometric quantification of oxygen has been demonstrated. The response of the sensor was quantified by both cyclic voltammetry and chronoamperometry. A range of O(2) contents (2-13% v/v) and RTIL layer thicknesses (from ca. 6 to 125 mum)...
