HPLC Column, NP Silica, 5um, 2.1mm ID x 150mm Length, 100A. Cogent Brand. 1 EA.
Additional Information:
Cogent NP Silica™ HPLC Columns are designed for normal-phase and HILIC separations of polar and hydrophilic compounds. Manufactured from ultra-high purity, low-metal-content 100 Å silica, this stationary phase is completely unmodified, providing the selectivity associated with USP L3 classified columns. NP Silica™ columns are widely used in established methods and new method development where traditional silica selectivity is required.
82561-15P-2 is packed with 5 µm NP Silica™ particles in a 2.1 mm ID x 150 mm format. The narrow internal diameter reduces solvent consumption while providing the traditional selectivity expected from unmodified silica. The 150 mm column length delivers increased resolving power and peak capacity compared to shorter columns, making it well suited for more demanding analytical separations.
The 2.1 mm ID x 150 mm format is well suited for HILIC applications, normal-phase chromatography, pharmaceutical analysis, quality control testing, and method development. Typical flow rates are approximately 0.2-0.3 mL/min. Standard HPLC systems used with 2.1 mm ID columns must be capable of delivering stable and reproducible low flow rates for optimum chromatographic performance.
