abstract: The authors describe the identification by infrared microtechniques (multi attenuated total reflexion) of the residues of eleven substituted ureas used as herbicides, after separation by thin-layer chromatography. The limitations of the method and the interferences from extracts of natural waters are discussed. In the most favourable cases the detection limit is 40 ppM (40 mug/l).
