Separation of aza-arenes by high-pressure liquid chromatography.
Fast, efficient liquid chromatographic separations of aza-arenes were obtained using both, reversed-phase, and adsorbent packings. Aza-arenes with 2-5 rings are separated within 20 minutes. Sample recovery is quantitative and permits subsequent uv and fluorescence spectrophotometric identifications. The detection limit for most aza-arenes was 1 ng with a 254-nm uv detector. An application to an air pollution problem demonstrates the usefulness of this approach.
