[Identification and quantitative determination of currently important plant protectants by HPTLC].
This systematic study describes the determination of approximately 150 pesticides (mainly insecticides and fungicides) on high-performance thin-layer chromatography (HPTLC) layers, using modern techniques for spotting and evaluation. Standardized mobile phases and reagents for visualization form the basis for the confirmation of gas-chromatographic results by HPTLC. The very high sensitivity of cholinesterase inhibition can be utilized only on plates coated with silica gel. Several other currently important pesticides can be separated on C-18 reversed phase layers and detected using silver nitrate-UV irradiation or chlorine-o-tolidine. Computer-assisted densitometric evaluation allows direct quantitative determination of the pesticides.
