4 Test principle

Flammable liquid fires or other physical evidence because it contains a double bond or a conjugated system and the electronic transition occurs, resulting in a range of special ultraviolet located

Intrinsic absorption, according to the spectral characteristics such as the number of peak absorption, location, shape and standard ultraviolet spectrum compared to determine or other flammable liquid fires

Evidence exists.
