中文摘要:
      建立了便携式声表面波气相色谱(GC-SAW)快速检测苯系物方法。在该条件下顶空测试: 检测器温度25℃,DB-5毛细管色谱柱:初始温度40℃,10℃/s程序升温至180℃。结果表明,氯苯、间二甲苯、苯乙烯、异丙苯保留时间分别为1.72、1.86、2.00、2.22s,检出限分别为:1.34、0.55、0.50、0.39 μg/L,测得RSD值为4.08%-5.98%,回收率为 82.7%-103.8%,且线性良好,线性相关系数为0.9946-0.9993。因此,该方法适用于水中苯系物的快速应急监测。
英文摘要:
      A method of benzene series rapid detection has been developed using gas chromatography with surface acoustic wave detector (GC-SAW). Benzene series was tested by headspaceSunder this condition. The SAW detector temperature was set at 25℃. The initial temperature of DB-5 capillary column was 40℃, and was temperature-programmed to 180℃ with the rate of 10℃/s. The results show that the retention times of chlorobenzene, m-xylene, styrene and cumene were 1.72, 1.86, 2.00, 2.22s respectively, the detection limits were 1.34, 0.55, 0.50, 0.39 μg/L respectively, and the RSD were in 4.08%-5.98%. The recoveries were 82.7%-103.8%, and the linearities were good,linear correlation coefficients were 0.9946-0.9993. Therefore, this method is suitable for benzene series rapidly emergency monitoring in water.
