Abstract
A GC method is described for the simultaneous determination of triazines and phenylureas in aqueous samples by large volume injection with a Programmable Temperature Vaporisator injector
(PTV) and ion trap detection (ITD). The analytical column (DB 5MS, 30 m, 0.25 mm, 0.25 mm) is connected to a pre-column (DB 5MS, 5 m, 0.25 mm, 0.25 mm) via a cross piece valve (MCS) to
prevent residual solvant vapour from polluting the analytical column. The 8 pesticides (4 triazines and 4 ureas) are determined by this method, the linearity is improved using 2 Fisher test. The
detection and the quantification limits are also determined for each compounds and are less than 0.10 mg/L which is the limit fixed by the ECC reglementation on drinking water.
