A gas liquid chromatograph (GLC) equipped with a nitrogen-phosphorus detector (NPD) was used for the analysis of 8 organophosphorus pesticides in milk: acephate, chlorpyriphos, chlorpyriphos-methyl, diazinon, methamidophos, methidation, phorate, pirimiphos-methyl. The isolation of these pesticides was performed by liquid partition followed by a cleanup with a solid phase cartridge. The limit of quantification (LOQ) and limit of detection (LOD) were respectively 5 ppb and 1 ppb for each compound. The method was finally tested on milk samples.

Abstract
A gas liquid chromatograph (GLC) equipped with a nitrogen-phosphorus detector (NPD) was used for the analysis of 8 organophosphorus pesticides in milk: acephate, chlorpyriphos, chlorpyriphos-methyl, diazinon, methamidophos, methidation, phorate, pirimiphos-methyl. The isolation of these pesticides was performed by liquid partition followed by a cleanup with a solid phase cartridge. The limit of quantification (LOQ) and limit of detection (LOD) were respectively 5 ppb and 1 ppb for each compound. The method was finally tested on milk samples.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
