HPLC Column, NP Amino, 5um, 4.0mm ID x 50mm Length, 100A. Cogent Brand. 1 EA. Special Order Item.
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 needed for retention and separation of compounds that can be difficult to retain using traditional reversed-phase chromatography. NP Amino™ is an excellent alternative for USP L8 methods and for new method development involving polar analytes.
68540-05P-4 is packed with 5 µm NP Amino™ particles in a 4.0 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 development, and high-throughput workflows where reduced run times are important.
The amino stationary phase is not end capped and is particularly useful for sugars, carbohydrates, organic acids, and other highly polar compounds containing hydroxyl or carboxylic acid functionalities. This column can be used in Normal Phase and HILIC chromatographic modes and is packed and shipped in normal-phase solvents, making it suitable for applications requiring alternative retention mechanisms to reversed-phase chromatography.
