Trying to figure out if the calibration solutions for a conductivity probe/meter must be of a similar nature to the system which will be measured. I can only find aqueous calibration solutions online, and the solvent systems that I need to monitor are ethanol and methanol based. If I use the aqueous calibration solutions, will my measurements in the organic systems be accurate?

$\begingroup$ I don't know of any fundamental theoretical reason why you would need to match solvents. However, it seems like a very easy empirical test! Make some lithium acetate solutions of known concentration in water, in methanol, and in ethanol, and then compare the results! $\endgroup$ – Curt F. Sep 28 '15 at 17:34
