Abstract
|
|
|
|
An instrument is described that can obtain directly the whole capacitance vs. potential curve and accurately even in dilute solutions using positive feedback for IR correction. Applying a small (7∼10 mV) triangular signal, controlled rectification of the resulting square wave using sample-and-hold circuit allows one to plot the corrected double layer capacitance over a wide potential range. Several illustrations involving the improved performance characteristics of its applicability are given and its limitations discussed.
