Versatile Reversed-Phase Selectivity for Everyday and Specialized Separations
ANPEL Reversed-Phase Columns provide a broad selection of stationary phases for the separation of non-polar to moderately polar compounds in liquid chromatography. The range includes conventional C18, C8, and C4 phases, together with aqueous-compatible, high-pore-size, aromatic-selective, fluorinated, shape-selective, core-shell, and application-specific column chemistries.
Reversed-phase chromatography is widely used across pharmaceutical analysis, food and beverage testing, environmental monitoring, chemical research, and routine quality-control workflows. Selecting the right stationary phase helps laboratories balance retention, selectivity, resolution, analysis time, and method robustness for the target analytes.
Explore the Reversed-Phase Range
Choose the Right Reversed-Phase Column
Begin with the analyte’s hydrophobicity and the intended mobile-phase conditions. C18 is often selected as a practical starting point for general reversed-phase method development. When less retention is required, C8 or C4 may be appropriate. For methods involving aromatic compounds, isomers, or compounds requiring alternative selectivity, Phenyl, Biphenyl, Phenyl-Hexyl, PFP, or C18/PFP phases can be considered.
For highly aqueous mobile phases, select an aqueous-compatible C18 phase. For compatible biomolecule or macromolecule workflows, a large-pore option such as C18-BIO may be more suitable. C30 and PAHs phases should be considered where shape selectivity or dedicated PAH-related analysis is required.
Select the Appropriate Column Format
After choosing the stationary phase, select the column dimensions and particle size according to the analytical objective. Shorter columns may support faster methods, while longer columns can provide additional resolving power. Smaller particle sizes are commonly selected for higher-efficiency methods when the system and operating conditions are compatible. Internal diameter, pore size, and column format should also be matched to sample loading, detector flow requirements, and the intended HPLC or UHPLC workflow.
Typical Applications
ANPEL Reversed-Phase Columns can be selected for pharmaceutical formulations and impurities, food and beverage components, environmental contaminants, organic chemicals, personal-care ingredients, natural products, PAHs, carotenoids, nucleotides, preservatives, and other compatible analytical separations. Refer to the relevant series page and method documentation to select the most appropriate stationary phase and configuration.
Important Selection Note
Always verify the selected column’s pH range, mobile-phase compatibility, temperature limit, pressure requirement, pore size, and current SKU availability before use. Product-specific specifications and application recommendations should be confirmed on the relevant series page and against the latest technical documentation.
