ReproSil Gold 200 C4 from Dr. Maisch HPLC GmbH is a high-purity silica HPLC column with a 200 Å pore size and a butyl bonded phase. The short alkyl chain provides reduced hydrophobic retention, enabling mild elution conditions that help preserve the structural integrity and biological activity of large proteins, enzymes, and biomolecules. The extra-wide pore size ensures optimal accessibility and mass transfer for high-molecular-weight analytes, while delivering sharp peak shapes, high resolution, and excellent reproducibility.
ReproSil Gold 200 C4 columns from Dr. Maisch HPLC GmbH deliver gentle, reproducible separations with wide-pore accessibility – the preferred choice for sensitive protein and biomolecule HPLC applications.
