Catalog Number - 82061-15P-4

Cogent NP Silica™ HPLC Columns are manufactured using ultra-high purity, low metal content, 100Å silica that remains completely unmodified, providing the native silica selectivity required for Normal Phase and HILIC chromatography. This widely used stationary phase is an excellent alternative for methods requiring USP L3 equivalent chemistry and is highly effective for the separation of hydrophilic and polar compounds that can be challenging to retain using reversed-phase HPLC methods.

82061-15P-4 is packed with 10 µm NP Silica™ particles in a 4.0 mm ID x 150 mm analytical format. The larger particle size generates substantially lower operating backpressure than smaller particle columns, allowing higher flow rates while maintaining reliable chromatographic performance. The 150 mm length provides increased retention and chromatographic resolution, making it particularly useful for analytical method development and routine separations requiring improved peak capacity.

The 10 µm particle size makes this column especially valuable for preparative method development, purification method scouting, and process scale-up studies. Because 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 reduce development time and simplify method transfer.
