Ammonium traces besides excess sodium using 940 Professional IC Vario and direct conductivity detection

contributed by Metrohm | 09/18/2013

The determination of low ammonium concentrations besides excess sodium is demanding due to the small retention time difference of these two cations. This Application Note shows direct conductivity detection as an ideal means to detect ammonium in a wastewater sample containing 400 mg/L sodium. AN-S-313 shows the analysis of nitrite traces.
