HPLC Column, NP Diol, Wide Pore, 10um, 4.0mm ID x 150mm Length, 300A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent NP Diol™ Wide Pore HPLC Columns are designed for Normal Phase and HILIC separations of larger hydrophilic and polar compounds. Manufactured using ultra-high purity 300Å silica bonded with a short hydrocarbon ligand containing a terminal diol functional group, this stationary phase provides reliable retention, excellent reproducibility, and improved accessibility for larger analytes. NP Diol™ Wide Pore is an excellent alternative for USP L20 methods and is well suited for the analysis of larger molecules that require enhanced pore access.
82060-15P-4-3M is packed with 10 µm NP Diol™ Wide Pore particles in a 4.0 mm ID x 150 mm format with a 300Å pore size. The larger 10 µm particle size allows operation at higher flow rates while producing lower backpressure than smaller particle columns. The 150 mm column length provides enhanced retention and resolution compared to shorter columns, making it suitable for more demanding separations, method optimization, and routine analytical applications involving larger molecules.
The NP Diol™ Wide Pore stationary phase is non-end-capped and is frequently selected as an alternative to unmodified silica columns due to its enhanced durability and broader solvent compatibility. The 300Å pore structure improves mass transfer and accessibility for larger molecules while maintaining effective retention of hydrophilic and polar compounds in both HILIC and Normal Phase chromatography. This column is particularly useful for large molecule applications requiring improved resolution and reproducible separations.
