| 中文摘要: |
| 采用内置式热解吸-气相色谱联用检测室内空气中总挥发性有机物, 介绍了内置式热解吸进样的优点。建立了苯、甲苯、乙酸丁酯、乙苯、对 ( 间 ) 二甲苯、苯乙烯、邻二甲苯、正十一烷等典型有机污染物的外标曲线, 各组分相关系数R 2 为 0.999 2 ～ 1, 考察了方法重复性,6 次平行试验的RSD为 0.8% ～ 1.4% 。 |

| The GC with built-inthermaldesorptionwasapplied fordetermination oftotalvolatileorganiccom poundsin indoorair. The advantageofbuilt-in thermaldesorptioninjection wasdescribed. Thestandard curvesof typicalorganicpollutantswereestablished such asBenzene, Toluene, Butylacetate, Ethylbenzene,p-Xylene, m-Xylene,o-Xylene, Styreneand Undecane. Thecorrelation coefficientsofcompounds R 2 ranged from 0.999 2to1. Therepeatability ofmethod wasobserved and RSD ofsix paralleltestsranged from 0.8% to1.4%. |
