ReproSil Gold 120 C4 from Dr. Maisch HPLC GmbH is a high-purity silica HPLC column with a 120 Å pore size and a butyl bonded phase. The shorter alkyl chain provides lower hydrophobic retention compared to C18 or C8 phases, enabling mild elution conditions that help preserve the structure and activity of proteins, peptides, and other sensitive biomolecules. The wide-pore design ensures efficient mass transfer and optimal accessibility for medium to large analytes, while delivering sharp peaks, high resolution, and excellent reproducibility.
ReproSil Gold 120 C4 columns from Dr. Maisch HPLC GmbH deliver gentle, reproducible separations with wide-pore accessibility – the ideal choice for sensitive protein and peptide HPLC applications.
