随着人民生活水平的提高，对居室居住环境污染的控制也越来越重视，特别是来源于室内各种涂料，黏合剂及各种人造板的总挥发性有机物(TVOC)作为异类污染物，组成复杂，由于它们单独的浓度低，种类多，对环境污染严重。国家建设部2001年下达了《民用建筑工程室内环境污染控制规范》GB50325-2001，对总挥发性有机物(TVOC)提出相应的控制规范，提出八种成分(苯，甲苯，对(间)二甲苯，邻二甲苯，苯乙烯，乙苯，乙酸丁酯，十一烷)作为应识别组份，检测方法采用气相色谱法。
浩瀚色谱（山东）应用技术开发有限公司探讨了在线《环境空气苯系物的测定活性炭吸附/二硫化碳解吸-气相色谱法》(HJ 584-2010)中存在的问题,并对此方法进行了改进.重新确定了方法检出限,使方法检出限更为合理;通过实验室计算出方法检测的浓度范围;改变了样品保存条件,使样品的保存周期,便于分析.

With the improvement of people&＃39;s living standards, more and more attention has been paid to the control of indoor living environment pollution, especially the total volatile organic compounds (TVOC) from various indoor coatings, adhesives and various wood-based panels as heterogeneous pollutants. The composition is extremely complex, and because of their low concentration and many species, they cause serious environmental pollution. In 2001, the Ministry of Construction issued the "Code for the Control of Indoor Environmental Pollution in Civil Construction Engineering" GB50325-2001, which proposed corresponding control specifications for total volatile organic compounds (TVOC), and proposed eight components (benzene, toluene, p-(m)xylene). , o-xylene, styrene, ethylbenzene, butyl acetate, undecane) as the components to be identified, the detection method adopts gas chromatography.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. discussed the problems existing in the online "Determination of Benzenes in Ambient Air by Activated Carbon Adsorption/Carbon Disulfide Desorption-Gas Chromatography" (HJ 584-2010), and improved the method. The detection limit of the method was re-determined to make the detection limit of the method more reasonable; the concentration range detected by the method was calculated by the laboratory; the storage conditions of the samples were changed, so that the storage period of the samples was longer, which was convenient for analysis.
