ReproSil-XR 120 C4 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and a butyl bonded phase. The short alkyl chain provides lower hydrophobic retention compared to C18 or C8, enabling milder elution conditions that help preserve the structure and activity of peptides, small proteins, and other sensitive biomolecules. With its combination of excellent peak symmetry, high efficiency, and batch-to-batch reproducibility, this column is an excellent choice for analytical and semi-preparative workflows in life science applications.
ReproSil-XR 120 C4 columns from Dr. Maisch HPLC GmbH deliver gentle yet highly efficient separations – the ideal choice for biomolecule analysis in reversed-phase HPLC.
