The Qualitative Analysis of the Selected Explosives using Thin-Layer Chromatography
Keywords:TLC, Explosive, TNT, RDX, HMX, Tetryl
A simple, economical and relatively quick method of thin-layer chromatography (TLC) has been applied to analyse four frequently used explosives, TNT, RDX, HMX and Tetryl that are a common part of significant military, industrial and improvised explosives. Silicon dioxide is proven to separate individual explosives at a stationary phase. Out of 38 tested, three types of two-component mobile phases consisting of petroleum ether and acetone in the ratio of 2:1 or 7:3 of a volume and hexane and acetone in the ratio of 2:1 of a volume are recommended. To detect explosives, the UV radiation with the wavelength of 254 nm is proposed.
