ReproSil 80 SAX from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with an 80 Å pore size and a strong anion exchange bonded phase based on quaternary ammonium functional groups. This phase offers strong ionic retention for negatively charged analytes, delivering high resolution and reproducible performance in analytical separations. The small-pore design provides a high surface area, enabling sharp peak shapes, excellent separation efficiency, and consistent results for ionic small molecules and acidic compounds.
ReproSil 80 SAX columns from Dr. Maisch HPLC GmbH deliver robust, high-resolution ion-exchange performance – the preferred choice for acidic and anionic small-molecule chromatography in HPLC.
