The description also works in the other direction: if the EIS data
shows a drop in phase angle in the low frequency range, than the
associated model is that of a growing pore.
Usually assigning the model and evaluating the low frequency
range is sufficient to get a “pass” or “fail” for screening purposes.
Should it be required, then fitting the data with an equivalent circuit
would typically involve a capacitance and a resistance term in parallel.
The resistance term changes in time, whereas the capacitance
term remains constant.
