A low-noise potentiostat, developed and built at NBS, is described. The instrument, which has built-in an ac current amplifier, is particularly suited for detecting small current fluctuations in the frequency range between 0.1 and 2000 Hz. The noise

To simplify the measurement of electrochemical noise in field applications, three identical electrodes, one acting as a reference electrode (RE), are often used. However, the intrinsic noise of the RE introduces errors in the noise resistance values

Removing direct current (DC) trends before calculating standard deviations and power spectral densities is a necessary operation, but the choice of method is probably one of the most diffi...

Measurement of the noise resistance (Rn) or frequency-dependent noise impedance (Zn), both derived from the fluctuations of current and voltage of electrodes corroding at the open-circuit potential, is more and more widespread for corrosion applicati

The relationship between electrochemical noise (EN) time records and the power spectral densities (PSD) derived from them was examined. It was shown how the PSD of EN consisting of a serie...

The fast Fourier transform and the maximum entropy method (MEM) provide algorithms for the estimation of the power spectral density (PSD) of fluctuations. Both have been employed for the analysis of electrochemical noise in corrosion studies, and cla

The errors introduced by the instrumental noise in electrochemical noise measurements can be considerable and not easily detectable in certain conditions. Errors arising in the measurement of noise resistance in corrosion research are discussed, with
