ReproSil 80 SAX-2 from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with an 80 Å pore size and an improved strong anion exchange bonded phase utilizing quaternary ammonium functional groups. Compared to the standard SAX version, SAX-2 offers enhanced selectivity, improved peak symmetry, and greater batch-to-batch reproducibility. The small-pore design ensures a high surface area, delivering sharp peaks, high resolution, and consistent retention for a wide range of acidic and anionic small molecules.
ReproSil 80 SAX-2 columns from Dr. Maisch HPLC GmbH deliver enhanced strong anion exchange performance – the ideal choice for precise and reproducible acidic and anionic small-molecule separations in HPLC.
