Summary Reversed-phase liquid chromatographic retention characteristics for the sixteen acyclic C1−C5 N-alkylbenzamide congeners were measured on various branched and linear, alkyl bonded hydrocarbon stationary phases. Retention factors, k′, were determined in acetonitrile-water mobile phase compositions on ethyl, n-octyl, n-dodecyl, n-octadecyl, 1-ethyladamantyl, 4-butyloctyl, and 2,4,4-trimethylpentyl stationary phases. Statistical analysis of the two main effects investigated — type of stationary phase and percentage of organic modifier (acetonitrile) in the mobile phase — described greater than ninety percent of the variability in the data for most of the comparisons. Selectivity effects due to variation in the mobile phase dominated the results.
