Quick Test for Accelerants after Steam Distillation
Gage-O® paste for gasoline detection is placed on a 3-mm diameter glass rod and inserted for 30 s into the water-organic interface of the distillate in the Barrett receiver after steam distilling the suspected residue. If accelerants such as gasoline, turpentine, paint thinner, or brush cleaner are present, a small white line, which fluoresces intensely with long wavelength ultraviolet radiation, appears. The remaining accelerant can be confirmed by separation with gas chromatography.
