Determination of Pesticide Residues in Vegetableby Capillary Gas Chromatography

Determination of pesticide residues in vegetable by capillary gas chromatography has many advantages, such as analysis of many kinds pesticides, good precision, accuracy results, short time and so on. Average recovery of α-666，β-666,γ-666,δ-666,ρ,ρ′-DDE,o,ρ′-DDT,ρ,ρ′-DDD,ρ,ρ′-DDT, fenpropathion, fenvalerate, deltamethrin is 98.9%,94.2%,106.1%,100.5%,97.3%,103.8%,95.7%,105.3%,95.6%,98.4%,102.8%, respectively, and the relative standard deviation of the precision peak propotion is 2.1%,2.9%,3.6%,2.0%,2.9%,4.3%,4.7%,3.1%,1.9%,2.3%,2.7%, respectively.
