Measurements of large impedances in a wide temperature and frequency range

Some observations on synthesis and electrolytic properties of nonstoichiometric calcium zirconate

“…Electrical properties of CaZrO 3 -based samples were also investigated by means of impedance spectroscopy method. The impedance was measured in the automated setup assembled on Solatron 1260 Frequency Response Analyser in frequency range 1-10 7 Hz and in the temperature range from 200 to 1000 • C. Impedance spectra were analysed by using the program Firdravn [23]. Prior to electrical measurement of samples, Pt porous electrodes were applied at both sides of every pellet (Heraus Germany, Pt paste fired at 850 • C/15 min).…”

A systematic approach toward error structure identification for impedance spectroscopy

“…As discussed in the previous section, regression of measurement models is sensitive to such discontinuities. Dygas and Breiter [36,41] have described methods that account for discontinuities caused by switching of current measurement circuitry. 5.…”

An integrated approach to electrochemical impedance spectroscopy

“…Use of dummy cells can help identify artifacts that are consistent with the Kramers-Kronig relations. As an alternative approach for identification of stochastic part of the error structure, Dygas and Breiter have shown that impedance instrumentation could, in principle, provide standard deviations for the impedance measurements at each frequency [9].…”
