摘要
建立了饲料中盐酸克仑特罗气谱 质谱联用检测方法 ,试样中的盐酸克仑特罗经提取、净化、衍生化 ,采用GC MS方法测定 ,外标法定量。研究表明 ,盐酸克仑特罗的线性范围为 0 .0 5～ 10mg/kg ,方法回收率为 84 .0 %～10 0 .1% ,最小检出限为 0 .0 1mg/kg。
An analytical method for Clenbuterol in feed by gas chromatography mass spectrum was described. Extract purification was based on Solid Phase Extract (SPE).The analytics were derivatized to trimethylsilyl (TMS) and detected by GC MS and quantitated by external standard method. The linear range is from 0.05 to 10mg/kg. Recovery is in the range of 84.0%～100.1%.The minimum detectable quantities is 0.01 mg/kg.
