民用建筑工程室内环境污染测定 详细信息：


名称：毛细管柱
固定液：二甲基聚硅氧烷
规格：50m*0.32mm
型号：HH-TVOC
应用：GB503252020民用建筑工程室内环境污染控制标准


为了预防和控制新建、扩建、改建的民用建筑工程室内环境污染，建设部制定了《民用建筑工程室内环境污染控制规范》。2002年3月1日，中华人民共和国建设部办公厅发文：建办质[2002]17号，印发了《关于加强建筑工程室内环境质量管理的若干意见》的通知，明确规定了：建立民用建筑工程室内环境竣工验收检测制度。建筑工程竣工时，建设单位要按照《规范》要求对室内环境质量检查验收，委托经考核认可的检测机构对建筑工程室内：氡、甲醛、苯、氨、总挥发性有机物化合物（TVOC）的含量指标进行检测。

滕州市浩瀚色谱仪器技术服务有限公司，研究了热解吸／毛细管气相色谱法测定室内空气和环境空气中多种挥发性有机物TVOC的分析方法。以HH-TVOC毛细管柱分离，氢火焰离子化检测器检测，取得较好的结果。本方法低检出限为0．5μg／m^3，相对标准偏差3．4％，加标回收率在85％～120％。

Indoor Environmental Pollution Measurement of Civil Construction Engineering
Indoor Environmental Pollution Measurement of Civil Construction Engineering Details:


Name: Capillary Column
Fixing fluid: dimethyl polysiloxane
Specification: 50m*0.32mm
Model: HH-TVOC
Application: GB503252020 Indoor Environmental Pollution Control Standard for Civil Construction Engineering


In order to prevent and control the indoor environmental pollution of newly-built, expanded, and rebuilt civil construction projects, the Ministry of Construction has formulated the "Code for Indoor Environmental Pollution Control of Civil Construction Projects." On March 1, 2002, the General Office of the Ministry of Construction of the People’s Republic of China issued a document: Jianbanzhi [2002] No. 17, issued a notice on "Several Opinions on Strengthening the Indoor Environmental Quality Management of Construction Projects", which clearly stipulates: the establishment of civil buildings Completion acceptance inspection system for the indoor environment of the project. When the construction project is completed, the construction unit shall inspect and accept the indoor environmental quality in accordance with the requirements of the "Code", and entrust an accredited testing agency to inspect the indoor environment of the construction project: the content of radon, formaldehyde, benzene, ammonia, and total volatile organic compound (TVOC) Indicators are tested.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. has studied the analytical method of thermal desorption/capillary gas chromatography for the determination of TVOC in indoor air and ambient air. It was separated by HH-TVOC capillary column and detected by hydrogen flame ionization detector, and good results were obtained. The minimum detection limit of this method is 0.5μg/m^3, the relative standard deviation is 3.4%, and the recovery rate of standard addition is 85%~120%.
