摘　　要：吸附管老化是影响挥发性有机污染物分析的重要因素,利用SC-10吸附管老化仪结合固相吸附-热脱附气相色谱质谱联用技术,研究SL-T007吸附管在不同老化条件下的老化效果。结果表明:在老化时间为45 min、老化温度为380℃、吹扫流量为90~100 L/min时,老化效果最好。稳定性实验表明:老化后的吸附管,用黄铜帽密封并包裹铝箔纸置于室温条件下保存12 d。该方法具有老化时间短,保存时间较长,操作简单等优点。The aging of adsorption tube was an important factor affecting the analysis of volatile organic compounds(VOCs).The aging effect of SL-T007 adsorption tube under different aging conditions was studied by using aging device of SC-10 adsorption tube coupled with solid phase adsorption-thermal desorption gas chromatography-mass spectrometry.The results showed that optimal aging effects could be obtained when the aging time,the aging temperature and the purging flow rate was 45 min,380℃and 90-100 L/min,respectively.Stability test indicated that,when sealed by brass cap and then wrapped by aluminum foil,the tube could be kept clean for 12 days at room temperature.The aging method reported here has advantages such as short aging time,long stability and easy operation and so on.
