Abstract An analytical scheme is presented which permits assessment of the photochemical significance of light-duty mobile source hydrocarbon emissions. The scheme incorportates both the mass and atmospheric reactivity of the hydrocarbon emissions. Analytical procedures supplementary to those defined for light-duty mobile source certification in the Federal Register are defined. The analytical procedures permit definition of four basic reactivity classes of hydrocarbons: Class I, nonreactive, including methane, ethane, acetylene, propane, and benzene; Class II, reactive, including the C4 and higher paraffins; Class III, reactive, including the aromatics except benzene; and Class IV, reactive, including the olefins. Gas chromatographic analysis of Class I hydrocarbons is described in detail.
