Respected All Research Members. Actulaay I faced the problem while analysis the EIS Data as i got the value of Z" negative. What should be the possible reason for this.
In most system, Z'' or Im Z is negative. Most papers use Z' and -Z'' as axis in a figure. This may lead you thought Z'' should be positive. If it is this case, just convert the data directly.
Sorry, I don't have papers. They should be very easy to be obtained, or you can also search EIS + some topic, then EIS figures and their papers will come. As for the fundmental theory, I personally recommend Bard's book and Electroanalytical Methods from springer.
