ReproSil Saphir 100 SAX from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 100 Å pore size and a strong anion exchange bonded phase based on quaternary ammonium functional groups. This chemistry provides strong ionic retention for negatively charged analytes, ensuring high resolution, excellent selectivity, and sharp peak shapes. Engineered for robustness and reproducibility, this column is well-suited for ion-exchange chromatography of polar and acidic small molecules in complex matrices.
ReproSil Saphir 100 SAX columns from Dr. Maisch HPLC GmbH deliver robust, high-resolution anion-exchange performance – the ideal choice for polar and acidic compound chromatography in HPLC.
