摘　　要： 采用自行设计的毛细管电泳电化学检测系统,对安痛定注射液中2组分安替比林和氨基比林进行了分离检测。在pH=9.0的30mmol/L硼砂缓冲溶液中,分离高压为20kV,进样时间为8s,检测电位为0.8V的条件下,安替比林的线性范围为0.5～100mg/L,线性系数为r=0.9992,检出限为0.01mg/L;氨基比林的线性范围为2～160mg/L,线性系数为r=0.9985,检出限为0.05mg/L。 On the self-constructed electrochemical detection system, antipyrinum and amidopyrine in injection antondint were separated and determined by capillary electrophoresis with amperometric detection （CE-AD）. Under the optimized conditions： a running buffer composed of 30 mmol/L Na2B4O7 buffer pH 9. 0, separation voltage 20 kV, injection time 8 seconds and detection voltage 0. 8 V, a linear relationaships between peak areas（Y） and mass concentrations（c） of the two analytes were established, with a determination limit of 0. 1 mg/L for antipyrinum and that of 0. 05 mg/L for amidopyrine, respectively.
