固体吸附-热脱附/气相色谱-质谱法测定室内木质门中挥发性有机化合物

Study on Contents and Components Characteristic of Volatile Organic Compounds in Indoor Wooden Door by Solid Adsorption-Thermal Desorption GC/MS

采用固体吸附-热脱附/气相色谱-质谱法对采集的25批次木质门进行总挥发性有机化合物(TVOC)测定,结果表明:3批次木质门的TVOC超过0.50mg/m^(2)·h,TVOC释放率大小与木质门的生产工艺关系密切,经分析发现,木质门释放的VOCs主要成分包括醛酮类、苯系物、酯类、醚醇类、烷烃类等多种溶剂、稀释剂和助剂。

The total volatile organic compounds(TVOC)of 25 batches of collected wooden door were determined by the solid adsorption-thermal desorption GC/MS,the results showed that,TVOCs of 3 batches of collected wooden door exceeded 0.50mg/m2·h,and the TVOC release rate had a close relationship with the production process of wooden door.Through the analysis,it was found that,main components in VOCs released by wooden door comprised various kinds of solvent,diluent,additive such as aldehyde ketones,benzenes,esters,ether alcohols,alkanes compounds.
