ReproSil Gold 200 from Dr. Maisch HPLC GmbH is a high-performance range of wide-pore, high-purity silica HPLC columns optimized for the separation of medium-to-large biomolecules, including proteins, enzymes, peptides, and glycoproteins. With a 200 Å pore size, these columns offer an excellent balance between mass transfer efficiency and surface accessibility, making them suitable for both bioanalytical and small-molecule applications.
The series includes multiple bonded phases – C18, C8, and C4 – to provide different levels of hydrophobic retention and selectivity, allowing precise tuning of separation conditions for diverse analyte types.
ReproSil Gold 200 columns from Dr. Maisch HPLC GmbH combine wide-pore accessibility with outstanding separation performance – the ideal choice for medium-to-large biomolecule chromatography in HPLC.
