建立了树脂工艺品中8种残留卤代烃的顶空气相色谱-电子捕获检测器(HS-GC-ECD)检测方法。对前处理方式、顶空及色谱条件进行了研究。结果表明在顶空温度130℃、平衡时间60 min、基体采用空白树脂工艺品的顶空条件下,检测树脂工艺品中的卤代烃可获得良好的定量结果。所建方法的定量限在0.001～0.2μg/g之间,回收率在90%～120%之间,相对标准偏差为1.3%～3.9%。
The headspace gas chromatography-electron capture detector (HS-GC-ECD) method for the determination of eight residual halocarbons in resin handicrafts was established. Pretreatment methods, headspace and chromatographic conditions were studied. The results show that good results of quantitative determination of halogenated hydrocarbons in resin handicrafts can be obtained under the condition of headspace temperature of 130 ℃ and equilibrium time of 60 min. The limit of quantification was between 0.001 ~ 0.2μg / g, the recovery was between 90% ~ 120% and the relative standard deviation was 1.3% ~ 3.9%.
