This article presents the experimental results of analyzing phenoxyacid herbicides and bentazone in water samples using automated on-line solid-phase extraction. The method can be used for frequent monitoring of contaminants in the river Rhine and drinking water samples.
This document details an automated method developed for monitoring Bentazone and phenoxyacid herbicides in drinking water and river samples, such as those from the Rhine. The method utilizes an automated on-line solid-phase extraction system controlled by the Varian 9200 Prospekt Controller.
