HPLC Column, Hyper Similars C8 Octyl, 3um, 4.0mm ID x 150mm Length, 150A. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Hyper Similars C8™ Octyl is a traditional reversed-phase HPLC stationary phase developed for laboratories seeking a high-quality alternative to established C8 methods. As part of the Cogent™ Similars product line, it uses high-purity Type-B spherical silica with a bonded octyl (C8) ligand and endcapping to provide reliable chromatographic performance and excellent method reproducibility. Its surface characteristics are designed to closely match those of legacy Hypersil® and Spherisorb® columns, making it particularly useful for method transfer and replacement applications.
62308-15P-4 is a 150 mm x 4.0 mm ID analytical column packed with 3 µm, 150Å Hyper Similars C8 particles. The 150 mm length provides an excellent balance of chromatographic resolution and analysis time, making it suitable for routine analytical testing, quality control, and method development applications. The 3 µm particle size delivers greater efficiency and sharper peak shapes than comparable 5 µm columns, although higher operating backpressure should be expected. The 4.0 mm ID format typically operates at approximately 0.8–1.5 mL/min on conventional HPLC systems and is often selected when reproducing legacy methods that specify 4.0 mm ID columns.
This USP L7 column is an excellent alternative for methods developed on Thermo Fisher Hypersil™ C8, Spherisorb®, and similar octyl phases. The C8 chemistry is ideal for hydrophobic and neutral compounds analyzed under reversed-phase conditions and is particularly useful when less retention is desired than with a C18 column. Common applications include long-chain fatty acids, pharmaceutical compounds, and method transfer projects requiring selectivity comparable to traditional C8 stationary phases. This Special Order Item is manufactured upon receipt of order and is subject to Special Order terms.
