HPLC Column, Nova Similars Phenyl, 4um, 4.0mm ID x 150mm Length. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Nova Similars Phenyl™ is a traditional reversed-phase HPLC stationary phase manufactured on high-purity Type-B spherical silica with a fully endcapped phenyl bonded phase. The stationary phase consists of a four-carbon linker terminating in a phenyl functional group, providing unique chromatographic selectivity through a combination of hydrophobic and π-π interactions. Designed as a cost-effective alternative to Waters™ Nova-Pak® Phenyl columns, it offers comparable chromatographic behavior for USP L11 methods while delivering the reproducibility and reliability required for routine analytical and method-transfer applications.
64424-15P-4 is a 150 mm x 4.0 mm ID analytical column packed with 4 µm Nova Similars Phenyl 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 4 µm particle size provides improved efficiency and sharper peak shapes than comparable 5 µm columns while maintaining moderate operating pressure on conventional HPLC systems. The 4.0 mm ID format is commonly selected for legacy methods and typically operates at approximately 0.8–1.5 mL/min.
This USP L11 column is particularly useful for aromatic compounds where phenyl selectivity can provide different retention and separation characteristics than traditional C18 phases. Common applications include pharmaceutical analysis, aromatic hydrocarbons, environmental testing, impurity profiling, and methods requiring enhanced aromatic selectivity through π-π interactions. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
