Ion chromatography interference
WebMobile-phase ion chromatography (MPIC) is a technique that combines ion-pair chromatography with suppressed conductivity detection. Ion-pair chromatog-raphy is commonly used in combination with UV detection, in which case it is referred to as reversed-phase ion-pair chromatography (RPIPC). MPIC has the Web28 feb. 2007 · An isocratic elution mode by non-suppressed ion chromatography was employed in all the experiments. The identification of each ion was performed by the injection of the solutions containing a single ion. The instrument was calibrated with blank and standards of F − and Cl − ions at concentrations of 0.1, 0.2, 1.0, 5.0 and 10 mg L …
