An evaluation of the use of laminar C-18 disks employed as part of the solid phase extraction process. Simultaneous capillary gas chromatography mass spectrometry determination of triazines, organochlorine pesticides, and polyaromatic hydrocarbons

摘要

The combination of solid phase extraction and gas chromatography - mass spectrometry enables fast and reliable analysis of pesticides residues in drinking water. The evaluation of analysis techniques is a priority for laboratories dealing with quality control. The ordinance 89-3 of the 1/3/89 fixes the maximum acceptable concentrations of micro-pollutants in drinking water including pesticides and chemically related substances belonging to highly diversified chemical families. This paper described a multiresidue analysis method of triazines, organochlorine pesticides and polyaromatic hydrocarbons, adapted from the method E.P.A. 525.2. This multiresidue method and especially the solid phase extraction process employing laminar C-18 disks, is evaluated together with relevant statistical tests as outlined in the NF XP T 90-210 procedure.
