Odd random phase multisine EIS for organic coating analysis

Electrochemical Impedance Spectroscopy and its Applications

“…Since this is known for each frequency, it can be corrected for by multiplying the calculated impedance at that frequency by FT-EIS allows for measurements of nonstationary systems evolving slowly with time or during a potential sweep. In addition, it allows for detecting and quantifying the presence of time variance and nonlinear distortions in experimental data [123][124][125][126][127]135]. In these experiments, a series of odd harmonics was applied from which every third or fourth frequency was removed.…”

“…. This method was applied to study organic coatings on Al [125]. The signal contained frequencies between 0.1 Hz and , where N denotes the frequency number, and randomized phases (see Sect.…”

Application of Electrochemical Impedance Spectroscopy to Ferri/Ferrocyanide Redox Couple and Lithium Ion Battery Systems Using a Square Wave as Signal Input

“…These methods using Fourier transformation are called FFT impedance or FT-EIS. It was reported that white noise [11,12], pseudo-random noise (pseudo-white noise) [12][13][14][15][16][17], pseudo-random signals [18], multi-sine waves (superimposed sine waves) [19,20], step signals [10,12,[21][22][23][24][25], and square pulses [26,27] can be applied to FFT impedance. An on-line FFT impedance measurement system using pseudo-white noise as the input signal was developed by one of our authors [14,15], and its application to in situ EIS was reported [15][16][17].…”

Investigation of the Adsorption Mechanism of Heterocyclic Molecules on Copper using Potentiodynamic ORP-EIS and In-situ Ramans pectroscopy

“…This measurement methodology is a continuation of our previous work on MMTD adsorption [11] where a random phase multisine EIS technique was used which provides less statistical information compared to ORP-EIS [25]. Due to the inherent stationary nature of EIS measurements this statistical information is indispensable.…”
