Abstract:Gas diffusion membranes are frequently used to transfer volatile protolytes from a donor to an acceptor solution. This transfer is attended by a change in [H+] or [OH− and an absorbance change of the acid-base indicator present. Conditions determining the linearity and the sensitivity of the calibration graphs are discussed.
