"Times New Roman"">当人们使用XY "Times New Roman"">胶拈剂时,感觉到有一种严重的刺激性气味,恶心,导致无法工作。为调查中毒原因,我们对该胶粘剂进行了分析。由于XY mso-hansi-font-family:"Times New Roman"">胶粘剂的样品不宜在GC "Times New Roman"">上直接进样测定其挥发性组份,这样就需要在分析前必须对此样品做复杂的预处理。为了避免采用萃取、蒸馏、浓缩分离手段所带来的烦琐、耗时、干扰大等诸多间题,采用顶空进样- GC技术鉴定物质中的挥发性组份,为寻求XY mso-hansi-font-family:"Times New Roman"">胶粘剂使人们中毒的原因提供了科学依据。
