顶空-气相色谱法测定纸类印刷品中16种挥发性有机物

Determination of 16 Volatile Organic Compounds in Paper Print by Headspace-gas Chromatography

提出了顶空-气相色谱法测定纸类印刷品中16种挥发性有机物(VOCs)的方法。选用三醋酸甘油酯为溶剂,对平衡时间及平衡温度进行优化。结果表明,本方法测定16种挥发性有机物的线性范围为0～100mg/m2,最低定量限为(10S/N)为0.005mg/m2,回收率为94.79%～101.77%,样品6次重复测定的峰面积的相对标准偏差小于5%。

A method of Headspace-gas chromatography was developed for volatile organic compounds in paper print. Chosen as the solvent triacetin, Optimal balance between time and equilibrium temperature. The results showed that, the determination of 16 volatile organic compounds was in the linear range of 0-100 mg/m2, a mininmm detection limit （10 N/S） was the 0.005 mg/m2. Recovery was 94.79 %-101.77 %, sample six times repeated measurements of the peak area relative standard deviation was less than 5 %.
