An Improved pC0, Microelectrode

By utilizing the recently developed glass-membrane pH microelectrode an improved pC0, microelectrode has been manufactured. The new pC0, microelectrode described here has been made with tip diameters ranging from 2 to 200 pm. In addition, the sensitivity (slope) was nearly theoretical, 56 to 60 mV/log pC0,; the response time was I-3 min. and the intercept stability (drift) was less than 3 mV/20-min time interval. Finally, the lifetime of this electrode was several days to a week when stored correctly. The most unique quality of this pC0, microelectrode was that the operational characteristics, tip diameter, sensitivity. and response time, could be controlled by adhering to predetermined design considerations.
