Abstract
The impedance of ionic solutions may be determined using a bridge circuit where the ionic solution forms one leg of the bridge circuit and a reference impedance characterized by a reference time constant forms a second leg of the bridge circuit. The bridge is driven by a switched DC voltage waveform. Measurement of the ionic solution is delayed after switching to allow the reference impedance to reach its asymptotic value. The reference impedance may be varied to reduce the reference time constant.
