Ion chromatography (IC) is a separation technique used to analyze and quantify ions in a water solution. It works by passing a liquid sample through a column packed with an ion exchange resins that selectively retains ions based on their charge and interaction with the stationary phase. The ions are then eluted and detected, typically by conductivity, allowing precise measurement of anions or cations in complex mixtures. This ion chromatography system (IC, Dionex ICS-2100) is able to analyze the water-soluble anions (Cl−, NO2–, NO3−, SO42−, HPO42−, C2O42−) cations (Na+, NH4+, K+, Mg2+, and Ca2+) extracted from the filters. Anions analyzed after separation on a Dionex AS18 column (4×250 mm). applying gradient elution at 1 mL min−1 with eluent KOH (23 mM). Cations analyzed using a CS12A-5μm (3×150 mm) column with a CSRS-300 4 mm suppressor. Separation was achieved under isocratic conditions with methane sulfonic acid (MSA) eluent (20 mM) and a flow rate of 0.5 mL min−1.
