顶空-气相色谱/质谱联用法测定接装纸中挥发性有机化合物

摘要

建立了同时测定烟用接装纸中20种挥发性有机化合物的定性定量分析方法--顶空-气相色谱/质谱联用法，优化了顶空-气相色谱/质谱仪检测参数。顶空取样针最佳温度160℃，传输线最佳温度为180℃，分流比优化为5：1。方法的回收率为90.17％～102.13％，RSD小于2.00％，全扫描的定性限为0.0065～0.1331 mg/m2、定量限为0.0218～0.4436 mg/m2，选择离子的定性限0.0001～0.0115 mg/m2、定量限为0.0003～0.0384 mg/m2。%A headspace-gas chromatography/mass spectrometry (HS-GC/MS) method was developed to simultaneously determine 20 volatile organic compounds (VOCs) in tipping paper. The optimum detection parameters were:needle temperature of 160℃, transfer temperature of 180℃, split ratio of 5:1. The recovery rate was between 90.17%and 102.13%, while RSD was less than 2.00%. The MS-Scan qualitative and quantitative detection limits were from 0.0065 to 0.1331 mg/m2 and from 0.0218 to 0.4436 mg/m2, respectively. The SIR qualitative and quantitative detection limits were from 0.0001 to 0.0115 mg/m2 and from 0.0003 to 0.0384 mg/m2, respectively.
