A study has been conducted to optimize the qualitative analysis of azaarenes by HPLC. Values of the capacity factors, k, of standards separated by reversed-phase gradient elution on a non-polar octadecylsilica adsorbent or by normal-phase isocratic elution on a polar aminopropyl-silica adsorbent were compared. Both methods enabled the separation of azaarenes containing 2–5 aromatic rings per molecule. Although analysis time was considerably less on the aminopropylsilica stationary phase, it was found that this column, as opposed to the C18 column, was deactivated more rapidly, and its performance changes after a few analyses of azaarene fractions isolated from organic extracts of airborne material.
