Ingelse BA, van Dam RC, Vreeken RJ, Mol HG, Steijger OM: Determination of polar organophosphorus pesticides in aqueous samples by direct injection using liquid chromatography-tandem mass spectrometry. J Chromatogr A. 2001 May 18;918(1):67-78.
It was demonstrated that four out of six of the very polar organophosphorus pesticides (OPs), i.e. acephate, methamidophos, monocrotophos, omethoate, oxydemeton-methyl and vamidothion, could not be extracted from water using commonly available SPE cartridges.
Large volume (1 ml) water samples were directly injected onto an RP18 HPLC column with a polar endcapping. |
