HPLC Column, Hyper Similars C18, 3um, 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.
62318-15P-4 is a 150 mm x 4.0 mm ID analytical column packed with 3 µm, 150Å Hyper Similars C18 particles. The 150 mm length provides an excellent balance between chromatographic resolution and analysis time, making it suitable for pharmaceutical analysis, routine testing, and method development. The 3 µm particle size produces higher efficiency and sharper peaks than comparable 5 µm packings, although higher operating backpressure should be expected. The 4.0 mm ID format is frequently chosen when reproducing legacy methods and typically operates at approximately 0.8–1.5 mL/min on conventional HPLC systems.
This USP L1 column is well suited for hydrophobic and neutral compounds requiring strong reversed-phase retention. Common applications include pharmaceutical assays, long-chain fatty acid separations, quality control testing, and method transfer from established C18 methods. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
