A Pachinger et al.
Journal of chromatography, 558(2), 369-373 (1991-10-11)
The main metabolite of the herbicide pyridate is 3-phenyl-4-hydroxy-6-chlorpyridazine (CL9673). A high-performance liquid chromatographic method with amperometric detection is described for determining CL9673 at residue levels in water samples. Sample preconcentration is performed by passage through a C18 extraction cartridge.
Markus Burghardt et al.
Journal of agricultural and food chemistry, 53(18), 7150-7155 (2005-09-01)
Sorption and diffusion of the herbicide pyridate and its metabolite CL9673 were measured in reconstituted cuticular waxes isolated from Chenopodium album L. and Hordeum vulgare L. (cultivar Igri) leaves. The compounds have the same basic chemical structure, except that pyridate
W Lindner et al.
International journal of environmental analytical chemistry, 16(3), 205-218 (1983-01-01)
For many reasons residue analysis of plant protecting chemicals is becoming of increasing importance. The demand of modern trace analysis techniques is to detect significantly and sensitively values down to levels in the ppb range or even less. Aggravating circumstances
