This International Standard specifies a high-performance liquid chromatography (HPLC) method for qualitative and quantitative determination of herbicides of various substance classes in soils. This method covers triazines including their related metabolites, phenyl urea compounds and other herbicides. Compounds are identified and quantified with UV-detection.
The limit of detection for triazines and phenyl urea compounds is - 0,01 mg/kg dry matter. It is dependent upon both the compound and the soil matrix.
