摘要
热脱附-气质联用法作为一种无损分析技术,可以用于测定函套中的挥发性物质。为此,用Tenax-TA吸附管对10种目标化合物进行吸附,在优化的色谱条件下,苯、甲苯、乙酸正丁酯、乙苯、间/对二甲苯、苯乙烯、邻二甲苯、正十一烷和糠醛等组分相关性良好。对实际样品进行测定,可以实现函套等装具中挥发性有害物质的分离分析。研究结果对纸质文献的保护有参考作用。
A non-destructive analysis method was established for the determination of volatile substances in folding cases using thermal desorption-gas chromatography/mass spectrometry.Tenax-TA tubes were used for the absorption and desorption of 10 target compounds.Under optimized chromatographic conditions,benzene,toluene,n-butyl acetate,ethylbenzene,m-xylene,p-xylene,styrene,o-xylene,n-undecane and furfural had good linear correlations.Samples in the laboratory were also obtained and analyzed.The results show that separation analysis of volatile hazardous substances can be achieved using this method.
