Twenty-fifth anniversary of the retention index system in gas—liquid chromatography

Analytical pyrolysis - an overview

A method of comparing selected ion profiles of fire debris extracts for the purpose of differentiating background residues produced by burning asphalt from liquid petroleum distillates is discussed. Passive headspace concentration (ASTM E 1412) has the capacity to fractionate asphalt condensates, resulting in the production of chromatographic patterns remarkably similar to fuel oils. By examining the alkenes produced when asphalt burns, the smoke condensates can be differentiated from kerosene or diesel fuel.
