HPLC Column, Hyper Similars C18, 5um, 4.0mm ID x 150mm Length, 150A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Hyper Similars C18™ is a traditional reversed-phase HPLC stationary phase manufactured on high-purity Type-B spherical silica with a fully endcapped octadecyl (C18) bonded phase. Designed as a cost-effective alternative to legacy Hypersil® and Spherisorb® columns, it offers comparable chromatographic behavior for USP L1 methods while providing the strong hydrophobic retention, reproducibility, and broad applicability expected from a conventional C18 stationary phase.
62518-15P-4 is a 150 mm x 4.0 mm ID analytical column packed with 5 µm, 150Å Hyper Similars C18 particles. The 150 mm length provides an excellent balance of resolution and analysis time, making it suitable for routine analytical methods, pharmaceutical testing, and quality control applications. The 5 µm particle size offers reliable performance with moderate operating pressure and compatibility with conventional HPLC systems. The 4.0 mm ID format is commonly used for legacy methods and typically operates at approximately 0.8–1.5 mL/min.
This USP L1 column is ideal for hydrophobic and neutral compounds requiring strong reversed-phase retention. Common applications include pharmaceutical analysis, long-chain fatty acid separations, method development, and routine analytical testing. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
