Catalog Number - 82061-25P-3M

Cogent NP Silica™ Wide Pore HPLC Columns are designed for the separation of large hydrophilic and polar compounds using both HILIC and Normal Phase chromatography. Manufactured from ultra-high purity, low metal content 300Å silica that remains completely unmodified, this stationary phase provides the native silica selectivity required for proteins, peptides, biomolecules, and other high molecular weight analytes. The wide pore structure improves analyte accessibility to the silica surface, making it highly effective for large molecule method development and challenging separations.

82061-25P-3M is packed with 10 µm NP Silica™ Wide Pore particles in a 4.6 mm ID x 250 mm analytical format. The larger particle size generates significantly lower operating backpressure than smaller particle columns, allowing the use of higher flow rates while maintaining reliable chromatographic performance. The 250 mm length provides maximum retention, peak capacity, and chromatographic resolution, making it an excellent choice for complex large molecule separations requiring enhanced resolving power.

The 10 µm particle size makes this column particularly valuable for preparative method development, purification method scouting, and process scale-up studies. The 300Å wide pore design provides improved accessibility for proteins, peptides, and other large molecules, while the stationary phase chemistry remains consistent across analytical, preparative, and purification column formats. Methods developed on this column can often be scaled directly to larger internal diameter columns with predictable chromatographic behavior, helping streamline method transfer and reduce development time.
