✦ Synopsis

The relative sensitivities of steam distillation, hot headspace and adsorption wire techniques for fire accelerant recovery were compared under conditions designed to simulate the more extreme casework conditions of tenacious adsorption of accelerant to fire debris. Hot headspace performed least well, requiring between twenty and a hundred times more accelerant for detection than the adsorption wire method. Steam distillation was of intermediate sensitivity. Confirmatory tests were devised to allow the adsorption wire method to be used without recourse to other techniques in case work. A case example is given.
