HPLC Column, NP Silica, 5um, 4.6mm ID x 100mm 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.
82561-10P is packed with 5 µm NP Silica™ particles in a 4.6 mm ID x 100 mm format. The 5 µm particle size provides excellent chromatographic performance while maintaining lower operating backpressures compared to smaller particle columns. The 100 mm length offers an excellent balance between analysis speed and chromatographic resolution, making it suitable for routine analytical and method development applications.
The 4.6 mm ID x 100 mm format is well suited for HILIC applications, normal-phase chromatography, pharmaceutical analysis, quality control testing, and method development. Typical flow rates are approximately 0.8-1.5 mL/min depending on mobile phase composition and application requirements.
