Determination of low concentrations of acetochlor in water by automated solid-phase extraction and gas chromatography with mass-selective detection
TL;DR: In this article, a gas chromatographic/mass spectrometric (GC/MS) method for determining acetochlor in environmental water samples was developed. The method involves automated extraction of the herbicide from a filtered 1 L water sample through a C 18 solid-phase extraction column, elution from the column with hexane-isopropyl alcohol (3 + 1), and concentration of the extract with nitrogen gas.
