Seventy-three samples of motor gasoline, were analyzed by gas chromatography-mass spectrometry.
Abstract
Seventy-three samples of motor gasoline, collected in winter 2010 from 8 Provinces across Canada, and representing 3 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 percent, 50 percent, 75 percent, 90 percent by volume), and as a residue (approximately 99 percent 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.
