ReproSil 70 C4 from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 70 Å pore size and a butyl (C4) bonded phase. The shorter alkyl chain provides reduced hydrophobic retention compared to C18 or C8 phases, enabling faster elution and shorter run times, while still delivering excellent resolution for hydrophobic small molecules. Its small pore size offers a high surface area, ensuring sharp peaks, high efficiency, and reproducible performance in routine analytical workflows.
ReproSil 70 C4 columns from Dr. Maisch HPLC GmbH deliver fast, efficient separations with excellent reproducibility – the ideal choice for high-throughput small-molecule HPLC applications.
