| 摘 要： | 在气相色谱法测定溶剂型木器涂料中正丁醇及苯系物(包括苯、甲苯及二甲苯)时采用了VF-200MS型号的毛细管色谱柱。由于此型号的毛细管柱具有较强极性,不仅能达到正丁醇与苯系物之间的有效而满意的分离,而且还能使苯系物(包括苯、甲苯、乙苯、二甲苯)之间和二甲苯的同分异构体之间的有效分离。测定中采用正戊烷作内标和用火焰离子检测器检测。此方法的检出限(2S/N)在1.7~3.5 ng之间。用一含有正丁醇的硝基漆样品按所提出的方法进行多次重复测定,并在此样品的基础上加入各被测化合物的标准后进行测定,从而对方法的回收率和精密度作了测试,测得其回收率在87.8%~100.0%之间,测定值的相对标准偏差(n=6)均小于2.5%。

| Abstract: | The capillary chromatographic column,VF-200MS,with high polarity was used in the GC separation and determination of n-butanol and benzene homologues(i.e.,benzene,toluene and xylene) in solvent-based paint used for wooden articles.n-Pentane was used as internal standard and FID detection was used in the determination.Due to high polarity of the VF-200MS column,effective and satisfactory separations were attained not only between n-butanol and benzene homologues,but also among benzene,toluene,xylene and ethyl... |
