摘要
建立了高效液相色谱-串联质谱法检测葡萄中嘧菌酯的残留分析方法。样品经乙腈和水混合溶液提取,净化后高效液相色谱-串联质谱仪检测,外标法定量。结果表明,嘧菌酯在葡萄中平均添加回收率为98.8%~105.4%,变异系数为0.5%~1.0%。
The method for determining azoxystrobin residue in grape was established based on HPLC-MS/MS.The sample was extracted with acetonitrile and water mixture,purified,and detected.The quantitative analysis of external standard calibration curves was used.The results showed that the average recoveries of azoxystrobin in grape were 98.8%-105.4%,the relative standard deviations were 0.5%-1.0%.The limit of quantification for azoxystrobin in grape was 0.02 mg/kg.
