Popis:	In this work we describe a new thin-gap microelectrode assembly and its use as an electrochemical detector for analytes in the gas phase. The conditions for maximum sensitivity and reproducibility (pretreatment of the microelectrode surface, applied potential, and signal-to-noise ratio) were studied. We show that the efficiency of condensation of the analyte from the gas phase in the thin gap between two parallel line microelectrodes which form the electrochemical “cell” is the major factor determining the sensitivity of the device.
