Abstract

Carbon dioxide was utilized as the mobile phase. The chromatographic system, interface, and plasma source are described. For the determination of chlorine, the near-infrared atomic emission line at 837.6 nm was chosen to avoid molecular emission band interferences in the visible spectral region. Chromatograms for mixtures of chlorine-containing compounds are illustrated. The calibration range was 3 orders of magnitude, and the chlorine detection limit was 40 pg/s
