    Abstract

    The chromatographic separation and quantitation of highly ionic species was a difficult problem until recently. Ion chromatography (IC) represents a solution to this analytical problem.

    Nonsuppressed IC offers a new alternative method to practitioners of IC. Since a suppressor column is not necessary for this method, the time required to regenerate the suppressor column is saved. Better chromatographic efficiency is achieved with the suppressor removed. Peak reversal, a problem associated with the suppressor column, is also eliminated. The sensitivity for Cl (0.5 ppm) is comparable to that of conventional suppressed IC. The sensitivities for NO3 (1.25 ppm) and SO42− (1.25 ppm) are only slightly less than those observed for the conventional technique.
