This paper compares the Agilent J&W DB-5ms Ultra Inert column with similar versions from four other column manufacturers with respect to their chromatographic behaviors for active analytes. Superior results were observed on the DB-5ms 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 chromato- graphic performance was obtained for a diverse group of compounds that included chlorophenols, organophosphorus pesticides and aromatic positional isomers demon- strating the applicability of the DB-5ms column for a wide range of applications.
