Abstract
A simple quantitative HPLC-UV method for the analysis of ethofumesate in fodder beet, soil and water samples is described. This method is based on a simple extraction step, gel-chromatographic and/or minisilica gel column clean up step and a separation step on a reversed phase column with uv-detection. The method is sensitive down to 10 μg/L in water and 50 μg/kg in plant and soil.
This approach shows recoveries between 90% and 110% in almost all matrices. Preliminary tests show that this method is also applicable for the analysis of ethofumesate in other plant materials.
