摘　　要：建立高效液相色谱法测定吡虫清(aCeTamiprid) 含量, 实验采用C18柱(250×4.6 mm)30%乙腈 + 70%水 (ph≈3), 流速0.8ml/min,uV检测波长为270 nm, 检测限为0.01mg/l,线性方程为 Y =2344.3X+30979.6, 相关系数r =0.9999 。方法回收率为96.2%～98.6%,相对标准偏差rSd=0.46%(n=6).Analytical methodology for determining levels of Acetamiprid has been established.A reverse HPLC system consisting of C18 column with a mixture of acetonitrile/water(30∶70) as the mobile phase was used.The flow rate was 0.80 mL/min and the UV detection wave-length was 270 nm.The limit of qualifications (LOQ) was 0.01 mg/L(r = 0.9999) with a recovery rate of 96.2%～98.60% and RSD of 0.46% for 6 samples.The relationship can be described using the linear equation: Y =2344.3X+30979.6.
