This unit undertakes examinations of Alcohol, Petroleum Products, and other material exhibits which require chemical examination. This unit also examines exhibits related to Vigilance Trap cases. Latest equipment such as Gas Chromatograph, High Performance Liquid Chromatography, High Performance Thin Layer Chromatography and Gas Chromatography-Mass Spectrometer, Gas Chromatograph-Head-Space are extensively used in case examination works.
In this unit all examinations related to firearms and ammunition are carried out. The scientists examine effectiveness of a firearm, whether a particular firearm was used for firing or not. In this unit test fire cartridges and bullets are compared to establish that the cartridge and bullet were fired from the suspected firearm or not.
