Abstract
A technique has been developed for the measurement of lead in gasoline in the range 0.002 to 5 g/U.S. gal. The method is based on the use of Campton Scattering as an internal standard, and on a comparison of the unknown with a blank and with a standard solution. A correction procedure has been devised which takes into account the dependence of the analysis on the carbon‐hydrogen ration of the gasoline. The method has an accuracy, for a single measurement, of ± 0.002 at the 0.002 g/U.S. gal. level to ± 0.1 at the 5 g/U.S. gal. level.
