Agilent J&W DB-5ms Ultra Inert columns were compared to similar versions from three column manufacturers with respect to their chromatographic behaviors for active analytes. Superior results were observed on the DB-5ms UI columns for basic compounds. Chromatograms depicting peak shape characteristics are presented to show how exceptional inertness leads to a significant reduction in tailing of active basic compounds for more accurate, reliable analytical results. Excellent chromatographic performance was obtained for a diverse group of compounds that included chlorophenols, organophosphorus pesticides, and aromatic positional isomers, demonstrating the applicability of the DB-5ms UI column for a wide range of applications.
