Abstract
Determination of 57 kinds of organochlorine, organophosphorus and pyrethroid pesticides using online gel permeation chromatography (GPC) purification and gas chromatography-mass spectrometry (GC-MS) in eight kinds of traditional Chinese herbal medicine were studied. Simultaneous full scan and selective ion monitoring mode for GC-MS was used for qualitative and quantitative analysis. The correlation coefficients were higher than 0.99, Limits of detection (LODs) for 57 pesticide residues were between 0.0003 and 0.006 mg/kg, the limit of quantification (LOQ) were between the range of 0.001-0.02 mg/kg. The recoveries of 57 kinds of pesticides were between 80.86 and 112.26 %, the relative standard deviations were between 2.84 and 8.57 %.
