摘　　要：为研究邻二甲苯吸附管作为校准替代物质的可靠性,通过TD-GC联用技术进行大量重现性实验、平行对照实验,并对数据结果进行分析,确定了邻二甲苯的校准曲线。得到邻二甲苯通过热解吸仪的解吸效率在85%以上,符合标准管使用规范的要求。通过耐贮藏性实验得到该标准管在1个月的储藏期内量值的变化小于10%。实验结果表明,邻二甲苯标准吸附管满足作为检测设备的校准替代物质的性能要求。In order to study the the reliability of the o-xylene adsorption tubes as alternative calibration material,a lot of repeated experiments are performed by using TD-GC combined technique. The calibration curve of o-xylene is also determined. The results show that the desorption efficiency of o-xylene through thermal desorption is above 85%,meeting the requirements for the use of specifications of standard tube. The change of o-xylene desorption is less than 10% after1 month storage period through storage resistance experiment. It indicates that o-xylene standard absorption tube can meet the performance requirements and be used as alternative calibration material.
