HPLC Column, NP Amino, 5um, 4.6mm ID x 50mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent NP Amino™ HPLC Columns are designed for normal-phase and HILIC separations of highly polar compounds. Manufactured using ultra-high purity silica bonded with a three-carbon propyl linker and terminal amino functionality, this stationary phase provides the selectivity required for retention and separation of compounds that can be challenging on traditional reversed-phase columns. NP Amino™ is an excellent alternative for USP L8 methods and for new method development involving polar analytes.
68540-05P is packed with 5 µm NP Amino™ particles in a 4.6 mm ID x 50 mm format with a 100Å pore size. The 5 µm particle size provides reliable performance with moderate backpressure, while the short 50 mm column length is well suited for rapid analyses, method scouting, and high-throughput workflows that benefit from reduced run times and solvent consumption.
The amino stationary phase is not end capped and is particularly useful for sugars, carbohydrates, organic acids, and other polar compounds containing hydroxyl or carboxylic acid functionalities. This column can be used in Normal Phase and HILIC chromatographic modes and is commonly selected during method development when evaluating alternative retention mechanisms. Packed and shipped in normal-phase solvents, this column is frequently used as a method scouting column.
