Distillation 04
Distillation 04 : As used in fire investigation a laboratory process utilized in the recovery and analysis of accelerants. In simple distillation, the evidence specimen is heated to vaporize the residue and the vapors are condensed to reform as a liquid. In the process of steam distillation, the residue recovered from the scene is flooded with water and heated to the boiling point. Steam and vapors are introduced into the process and the condensed results are then separated. The accelerant, if any, is then identified. Vacuum distillation is a process in which any accelerant present in the suspected specimen is removed by simultaneous application of suction and heat
