Finit is a common insecticide generally used to control a variety of insects in homes. Routinely it is analysed by Gas Liquid Chromatography (GLC) and High Performance Liquid Chromatography (HPLC). An attempt has been made to develop a new method for analysis of finit in urine samples using Thin Layer Chromatography (TLC) technique which is inexpensive, accurate and non-destructive. Finit was extracted from urine using solvent extraction methods and then identified on the TLC plates. For detection on developed plates, palladium chloride, silver nitrate, iodine vapour and bromophenol blue were used which successfully increased the sensitivity without dispensing with the simplicity of the method. The method developed is simple, inexpensive, accurate and non-destructive that allows for sensitive and reproducible analysis of finit.
