A moving band interface is used to separate HPLC solvent from analyte before introduction into a microwave-induced plasma atomic emission detector. Spectral scans indicate that all detectable solvent is removed prior to analyte introduction. Analyte memory effects are not detectable. Chlorine element selective detection limits are 140,410, 220, and 770 pg/s for 9-chlorofluorene, p-chlorobiphenyl, 4-chlorobenzophenone, and [alpha],[alpha]'-dichloro-o-xylene, respectively. If the vaporization region is heated significantly, chlorine selective response is dependent upon the boiling point of the compound due to analyte volatilization before it reaches the detector. 18 refs., 8 figs., 2 tabs.
