摘　　要：基于气相色谱-电子捕获检测器法对11种代表性多溴联苯醚进行分析,考察不同类型气相色谱柱对多溴联苯醚分离分析的影响.结果表明:色谱柱极性是影响分离和响应的主要因素,极性较大的固定相上多溴联苯醚各单体的保留时间变长,响应降低,尤其是高取代多溴联苯醚的响应受到的影响最大.柱长较短、液膜较薄的色谱柱有助于高取代多溴联苯醚的分析.不同品牌的色谱柱受生产工艺的影响,对多溴联苯醚的响应产生较大影响.11 representative polybrominated diphenyl ethers(PBDEs) were analyzed based on the gas chromatographyelectron capture detector method, and the effects of different types of gas chromatographic columns on the separation and analysis of PBDEs were investigated. The results showed that the polarity of column is the key factor affecting the separation and response. On the stationary phase with stronger polarity, the retention time of each PBDEs monomer became longer and the response decreased, especially the response of highly substituted PBDEs was most affected. The column length and thickness stationary phase also have significant effects on the PBDEs analysis. Short column with thin stationary phase were suitable for the analysis of 11 PBDEs. Different brands of columns were affected by the production process and have a greater effect on the response to PBDEs.
