Survey of Canadian Gasoline (Winter 2010)

Abstract

Seventy-three samples of motor gasoline, collected in winter 2010 from eight provinces across Canada, and representing three different grades from 18 different refiners/retailers, were analyzed by gas chromatography-mass spectrometry. Each sample was analyzed in its unevaporated state, at four different levels of evaporation (25%, 50%, 75%, 90% by volume), and as a residue (approximately 99% evaporated). The resulting total ion chromatographic patterns and extracted ion profiles from these samples were compared and differences discussed in the context of identifying gasoline recovered from a fire scene
