Methods of Fire Debris Preparation for Detection of Accelerants.

Abstract

Forensic scientists use various techniques to separate accelerants from fire debris samples before instrumental identification of added fuels. Among the choices available, traditional micro-distillation, steam distillation, vacuum distillation, headspace, heated headspace, and several vapor adsorption/desorption methods provide various advantages and disadvantages. This communication reviews the development of these techniques from the 1950s and comparison studies performed.
