Notes:
Polarized microelectrodes were utilized as sensing devices, analogous to the human olfactory hairs, for qualitative and quantitative responses to volatiles. The measured response current is attributed to the interaction of a volatile with an electrical double layer at the electrode interface. The use of different microelectrode metals, electrolytes, and impressed voltages makes possible different electrical double-layer phenomena. With the use of only a few of the many possible combinations of electrode metals, electrolytes, and impressed voltages, differential-response sensitivity was obtained for a variety of volatiles at any given microelectrode condition. A comparison of the responses of several odorants at a number of different electrode conditions demonstrated a differential-response specificity similar to that thought to occur in the human at different olfactory receptor sites.
