ReproSil 70 is a fully porous, high-purity silica HPLC column group from Dr. Maisch HPLC GmbH, featuring a 70 Å pore size specifically optimized for the separation of small molecules in pharmaceutical, chemical, and environmental analysis. The smaller pore size increases surface area, providing strong retention and high efficiency for low-molecular-weight compounds.
Available with a wide range of bonded phases, including C18, C8, CN, NH₂, and phenyl, ReproSil 70 offers flexibility for reversed-phase, normal-phase, and polar interaction chromatography.
ReproSil 70 columns from Dr. Maisch HPLC GmbH provide strong retention and high resolution – the ideal choice for analytical HPLC of low-molecular-weight compounds.
