Catalog Number - 82560-P50-50-3M

Cogent NP Diol™ Wide Pore Process HPLC Columns are designed for large-scale purification, process development, and production-scale chromatography involving larger polar and hydrophilic molecules. Manufactured using ultra-high purity 300 Å silica bonded with a short hydrocarbon ligand containing a terminal diol functional group, this stationary phase provides reproducible retention, excellent durability, and broad solvent compatibility. The non-endcapped surface chemistry offers selectivity consistent with USP L20 classifications, making it an excellent choice for established methods and process-scale method development involving larger molecular weight analytes.

82560-P50-50-3M is packed with 5 µm NP Diol™ Wide Pore particles featuring a 300 Å pore size in a 50 mm ID x 50 mm process-scale format. The wide pore structure improves accessibility for proteins, peptides, and other higher molecular weight compounds while maintaining excellent retention of hydrophilic and polar compounds. The large internal diameter provides excellent sample loading capacity while the shorter column length minimizes run times and solvent consumption. NP Diol™ Wide Pore columns are frequently selected as alternatives to unmodified silica columns because they often provide improved robustness and compatibility with a wider range of solvents while maintaining similar retention characteristics for many applications.

The 50 mm ID x 50 mm format is ideal for rapid process-scale HILIC and normal-phase chromatography applications involving proteins, peptides, and other larger molecules. Typical flow rates are approximately 80-140 mL/min depending on mobile phase composition, system pressure limitations, and application requirements. A specialized process or preparative HPLC system capable of high flow rates and large sample loading is required for optimum performance.
