Several workers have described the thin layer chromatographic technique for the determination of organophosphorus pesticides(32-44) as well as chlorinated pesticides(45-56). 

Figure 3 shows separation of some organophosphorus insecticides by thin-layer chromatography, and Figure 4 shows a chromatogram of some organochlorine insecticides in soil extracts.

Methods 17 and 18, respectively, determine Cyasorb UV 531 (2-hydroxy-4-n-octoxybenzophenone) in polyolefins by direct infrared spectroscopy and thin-layer chromatography. Phenolic and organophosphorus type antioxidants do not interfere in these procedures. Method 19 describes an ultraviolet spectroscopic method for the determination of Tinuvin 326 ultraviolet absorber in polypropylene.
