HPLC Column, Hyper Similars C18, 5um, 4.0mm ID x 50mm 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.
62518-05P-4 is a 50 mm x 4.0 mm ID analytical column packed with 5 µm, 150Å Hyper Similars C18 particles. The short 50 mm length is optimized for fast analyses, rapid equilibration, and high-throughput workflows. The 5 µm particle size provides reliable performance with moderate operating pressure and compatibility with conventional HPLC systems. The 4.0 mm ID format is often selected for reproducing 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, quality control testing, and fast analytical methods where speed and reproducibility are priorities. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
