摘要：
A new approach for fast detection of organophosphorus pesticide like dichlorvos in cabbage using solid phase microextraction (SPME) coupled with tin dioxide gas sensor was investigated. In comparison the experiments of guide sample of dichlorvos, this method which employed only one SnO2 gas sensor rather than an array of sensors in a rectangular temperature mode could perform the qualitative analysis. The quantitative analysis was performed using polar plots and peak area. (C) 2004 Elsevier B.V. All rights reserved.
