选择并表征了一种用于热脱附-GC/MS分析空气中挥发性有机物（VOC）和邻苯二甲酸酯（PAE）的吸附剂。将商业吸附剂TenaxTA和Carboxen 1000的组合依次装入解吸管中，通过邻苯二甲酸二乙基己酯（DEHP）应用于具有宽沸点的化合物，如乙醇。确认了分析结果的校准线性范围为10 - 500 ng，相关系数为0.999 - 1.000，VOC的重复性为1.5 - 2.0%，PAE的重复性为2.2 - 6.2%。检测限为0.07 ~ 2.67 ng/3升，或甲苯的检测限为0.02 μg/m3。用制备的管，采样的空气中的VOC和PAE在室内空气和从建筑材料的排放气体中的同时分析进行。
A sorbent for the thermal desorption-GC/MS to analyze volatile organic compounds (VOC) and phthalic acid esters(PAE) in air was selected and characterized. The combination of commercial sorbents of TenaxTA and Carboxen1000 packed in sequence into a desorption tube was applied to compounds with a wide boiling point, such as ethanol, through diethyl hexyl phthalate (DEHP). The analytical results were confirmed for the linearity of the calibration over a range of 10∼500 ng with a correlation coefficient of 0.999∼1.000, and also for a repeatability of 1.5∼2.0% to VOC and 2.2∼6.2% to PAE. The detection limit was found to be 0.07∼2.67 ng for 3 liters, or a detection limit of 0.02 μg/m3 for toluene. With the prepared tube, of sampled air a simultaneous analysis of VOC and PAE in indoor air and in the emitted gas from the building materials was performed.
