Chiral Columns
Reliable Resolution for Enantiomers and Stereoisomers
ANPEL Chiral Columns are designed for the separation of enantiomers, diastereomers, and other stereoisomeric compounds that cannot be resolved by conventional achiral stationary phases. The current CNWChiral range includes Amy-S, Cel-J, and RS-D series, providing distinct chiral recognition mechanisms for analytical method development and routine enantiomeric analysis.
Chiral chromatography is essential when the stereochemical composition of a compound affects its biological activity, safety, purity, or regulatory status. By creating different interactions with each enantiomer, a chiral stationary phase allows the two mirror-image forms to be retained differently and separated chromatographically.

Choosing the Right Chiral Column
Chiral-column selection is strongly dependent on the molecular structure of the analyte and cannot be predicted reliably from achiral chromatographic behavior alone. A practical starting point is to screen more than one chiral stationary phase using representative mobile-phase conditions, then optimize the phase that provides the best balance of retention, resolution, peak shape, and analysis time.
Consider the functional groups, polarity, acid-base properties, and solubility of the analyte when selecting the initial screening conditions. Mobile-phase composition, solvent modifier, flow rate, temperature, and sample solvent can all influence enantiomeric resolution. The recommended conditions should be validated for the selected column series before routine use.
Typical Applications
ANPEL Chiral Columns can be selected for enantiomeric purity testing, asymmetric-synthesis monitoring, pharmaceutical development, agrochemical analysis, chemical research, food and flavor analysis, and other workflows requiring stereoisomeric separation. Refer to the relevant CNWChiral series page for application-specific guidance and compatible operating conditions.
Important Selection Note
Chiral stationary phases can be sensitive to solvent history and operating conditions. Do not switch between incompatible mobile-phase systems without following the product-specific equilibration and flushing instructions. Always verify solvent compatibility, pH limits, maximum operating pressure, temperature range, and current SKU availability before use.
