Ion chromatography

Example of the analytical setup: Equipment: Dionex ICS-3000;   Guard Column: Dionex IonPac AG14A (4x50 mm);   Analytical Column: Dionex IonPac AS14A (4x250 mm);   Elution: Isocratic;   Eluent: 1 mM NaHCO_3, anionic: 8mM Na₂CO_3;   Eluent flow: 1.0 mL/min;   Temperature: 30 °C;   Injected volume: 25 μl;   Detector: Conductivity detector;   Suppressor: ASRS 300, 35 °C, 43 mA.

Example of an ion-chromatogram

The presence of selected anions is determined on the basis of specific peaks. Impurities can be detected down to the detection limit in the range of 10^-5 M.

Ion chromatography is performed as a non-GLP service
