摘要
通过美国Entech公司Summa罐采集大气样品,7100型大气预浓缩系统提取和富集样品中的挥发性有机物,省去了繁琐的有机物提取和净化工序,避免和有机溶剂接触,将样品直接输入气质联机进行分析。利用这种方法定性分析了某油罐区的大气成分,结果表明该地区大气中含有成分复杂的环己烷、苯和萘的衍生物,这些化合物的浓度远远大于居民区同类化合物的含量。
Gather atmosphere sample by Summa pot provide American Entech Corporation, 7100 atmospheric pre-eoncentration system withdraws and concentrates the volatile organic in the sample, has omitted the tedious organic extraction and the purification working procedure, avoids the contact with organic solvent, analysis the sample directly by GCfMS. Using this method analysis qualitatively some atmospheric constituent near by oilcans, had indicated finally the atmosphere here includes complex cyclohexane, the benzene and the naphthalene derivatives, these compound＇s density is bigger than that of residential area.
