Abstract
A method and apparatus for measuring trace amounts of lead alkyls in gasoline wherein a small sample of the gasline is injected into a vaporizer, with a carrier gas transporting the sample through the vaporizer to a filter that separates the interfering olefins and aromatic components from the lead alkyls in the sample. The discharge from the filter is supplied to an electrochemical cell of a type known as a galvanic sensor whose output signal is integrated or otherwise utilized to obtain a measurement of the quantity of lead alkyls in the sample.
