Abstract
The portable “Uni-Jet” Lead-In-Air Analyzer was revised to provide constant rate collection of tetraethyl (TEL) and tetramethyl lead (TML). Reliable results from monitoring leaded gasoline storage tanks, cleaning and decontamination procedures, were obtained by drawing a two-cubic-foot sample during twenty minutes through methanolic iodine. The aspirating unit powered by non-flammable “Freon-12” has been used widely in fire and explosion hazard areas.
