建立同时分析人工皮革中可能存在的22种挥发性有机物的分析方法。利用吹扫捕集方法富集待测组分,用气相质谱进行分离和定性定量。采用正交试验法优化吹扫捕集仪器的最佳条件,同时优化了22种组分分离的气相质谱条件;最佳条件下建立的方法的线性范围为5.0～100.0μg/mL,检测限在2.0～15.0μg/mL之间,最小检测浓度为0.004～0.025mg/m2,加标回收率高于80%,RSD(n=6)低于10.7%。 A method for the simultaneous analysis of 22 volatile organic compounds that may exist in artificial leather was established. The components to be tested were enriched by purge-and-trap method, and separated and quantified by GC / MS. The optimum conditions of purifying and trapping equipment were optimized by orthogonal test, and the GC conditions of 22 components were optimized. The linear range of the method was 5.0-100.0μg / mL under optimal conditions. The detection limit was between 2.0 ~ 15.0μg / mL, the minimum detectable concentration was 0.004 ~ 0.025mg / m2, the spiked recoveries were higher than 80% and RSD (n = 6) was lower than 10.7%.
