摘　　要：采用气相色谱-质谱联用仪,用同一浓度的标准物质、不同的进样量,外标法测定了工业乙烯、丙烯中的痕量砷烷、磷烷。砷烷、磷烷的测定下限均为20μL·m^-3,砷烷浓度在100~500μL·m^-3时,相对标准偏差最大为1.88%,加标回收率最大为104.6%。磷烷浓度在100~500μL·m^-3时,相对标准偏差最大为1.87%,加标回收率为100.62%。Trace arsenic and phosphorus in industrial ethylene and propylene was determined by GC-MS.The lower limit of arsine and phosphane was 20μL/m^3.When the arsine concentration was 100~500μL/m^3,the maximum RSD was 1.88%and the maximum recovery rate was 104.6%.When the Phosphorus concentration was 100~500μL/m^3,the RSD was 1.87%and the recovery was 100.62%.
