啶虫脒在西兰花中的残留测定

Determination of Acetamiprid Residues in Broccoli

应用气相色谱电子捕获检测器对西兰花中啶虫脒的残留量进行了测定,在柱温220℃、进样口温度280℃、检测器温度300℃、柱压力10psi的色谱条件下,回收率为81.4%～103.2%,最低检出质量分数为0.001mg/kg。该法能够满足农药残留检测的要求。

Acetamiprid in broccoli was determined by GC with ECD. Under the column temperature was 220 ℃, injection temperature was 280 ℃, detector temperature was 300 ℃ and column pressure was 10psi, the recoveries were 81.4-103.2%. The minimum detectable quality of acetamiprid was 0.001 mg/kg. This method can meet the residues determination.
