ReproSil-XR 120 SAX from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and a strong anion exchange (SAX) bonded phase containing quaternary ammonium functional groups. This chemistry provides strong ionic retention for negatively charged analytes, delivering high resolution, excellent selectivity, and sharp peak shapes in ion-exchange chromatography. Engineered for robustness and reproducibility, this column is suitable for both isocratic and gradient separations in pharmaceutical, environmental, and food analysis.
ReproSil-XR 120 SAX columns from Dr. Maisch HPLC GmbH deliver robust, high-resolution anion-exchange performance – the ideal choice for acidic and polar compound analysis in HPLC.
