✦ Synopsis

However, the MIPD is prone to solvent extinguishment when packed columns are employed and requires solvent vent valves, which add to the coinplexityin design [13,15] Capillary column systems do not require the valves

The performance of the gas chromatography / alternating current plasma detector as a selective detector for organolead compounds is investigated. The helium make-up flow rate and the spatial position from which the lead emission is viewed, have an effect on the detector response. The detection limit for tetrabutyl lead was established as130 pg/s and the leadselectivityratio was found to exceed 13,800. Some applications of organolead determination in complex matrices were also studied in order to demonstrate the selectivity and sensitivity of the alternating current plasma detector.
