摘　　要：应用气相色谱-串联质谱法(GC-MS/MS)测定玩具产品萃取液中10种有机锡化合物。试样用胃酸模拟液萃取,经四乙基硼酸钠衍生后,采用多反应监测(MRM)模式进行测定。结果表明:10种有机锡化合物的质量浓度均在1.0mg·L^(-1)以内呈线性,方法的检出限(3S/N)在0.065~2.6μg·kg^(-1)之间。回收率在85.1%~103%之间,相对标准偏差(n=6)在3.9%~10%之间,方法能满足玩具产品中有机锡化合物含量的测定。CA-MS/MS was applied to the determination of 10 organic tin compounds in toy products. The sample was extracted with simulated gastric acid, and the extract was derivatized with sodium tetraethyl borate and determined by CA-MS/MS under the mode of multi reaction monitoring （MRM）. As shown by the results, linear relationships between values of peak area and mass concentration of the 10 organic tin compounds were obtained in the same range within 1.0 mg·L^-1 , with detection limits （3S/N） in the range of 0. 065-2. 6 μg·kg^-1. Recovery and precision of method were tested by standard addition method, giving values of recovery in the range of 85.1 %- 103%, and RSDs （n=6） in the range of 3. 9%- 10%. This method was proved to be satisfactory for the determination of organic tin compounds in toy products.
