摘要
建立了气相色谱/质谱联用直接分析胶黏剂中苯系物的方法。采用选择离子扫描及内标标准曲线法定量分析了胶黏剂中苯、甲苯和二甲苯的含量。实验证明本方法简便、快速、灵敏、重现性好。方法的回收率92.3%-100.4%,三次测定的相对标准偏差范围为1.45%-4.58%。
Established a gas chromatography/mass spectrometry direct analysis method of benzene series in the adhesive. Used selected ion scanning and standard curves of internal standard method for the quantitative analysis for benzene,toluene and xylene in adhesive content. Experimental results showed that this method was simple,rapid,sensitive and reproducible. Recoveries of the method ranged 92.3% to 100.4%,the relative standard deviations of three measures were in the range of 1.45%-4.58%.
