Abstract:

Non-linear calibration is one major drawback of suppressed conductivity ion chromatography and thus, it has been subjected to intensive investigations over the last two decades. The investigations are mostly confined to anion chromatography using weak base eluents like carbonate because the extent of non-linearity is proportional to dissociation constant, Ka, of the suppressed eluate.
