The Use of Narrow Gap Line Microelectrodes as Sensitive and Species Selective Gas Chromatographic Detectors

Abstract

In this work we describe a new microelectrode assembly and its use as a sensitive electrochemical gas chromatographic detector. The conditions of operation of this device, i.e. pretreatment of the microelectrode surface, applied potential, and signal-to-noise ratio were studied in order to achieve maximum sensitivity and reproducibility. Condensation of the analyte in a thin gap between two parallel line microelectrodes comprising the electrochemical cell is considered to be the factor determining the sensitivity of the device.
