METHOD OF COMPENSATION OF SERIES ACTIVE RESISTANCE OF ELECTROCHEMICAL CELL IN VOLTAMMETRY Russian patent published in 1998 - IPC

FIELD: medicine; metallurgy; electronics; ecology. SUBSTANCE: to improve sensitivity and accuracy of voltammetric measurements, due to removal of noncontrolled phase shift in cell circuit (phase-sensitive AC voltammetry), acceleration of recharging of indicating electrode double-layer capacity (pulse voltammetry), removal of distortion (in DC voltammetry), compensation is performed by introduction of common or local positive feedback, the depth of which is set by maximum relation of value of higher-frequency harmonic current passing through cell and value of low-frequency harmonic current caused by low harmonic voltages applied to electrochemical cell. Full compensation of cell series resistance is obtained at maximum value of the above-indicated relation. EFFECT: more effective compensation. 2 cl, 2 dwg
