TVOC是“Total Volatile Organic Compounds”的英文缩写,意思是总挥发性有机化合物。
室内空气品质的研究人员通常把他们采样分析的室内有机气态物质称为VOC,它是Volatile Organic Compound三个词diyi个字母的缩写;各种被测量的VOC被总称为总挥发性有机物TVOC(Total Volatile Organic Compounds)。
TVOC是三种影响室内空气品质污染中影响较为严重的一种。TVOC是指室温下饱和蒸气压超过了133.32Pa的有机物,其沸点在50℃至250℃,在常温下可以蒸发的形式存在于空气中,它的毒性、刺激性、致癌性和特殊的气味性,会影响皮肤和黏膜,对人体产生急性损害。世界卫生组织(WHO)、美国国家科学院/国家研究理事会(NAS/NRC)等机构一直强调TVOC是一类重要的空气污染物。 美国环境署(EPA)对VOC的定义是:除了一氧化碳,二氧化碳,碳酸,金属碳化物,碳酸盐以及碳酸铵外,任何参与大气中光化学反应的含碳化合物。

浩瀚色谱(山东)应用技术开发有限公司,采用Tenax复合管采样,热脱附仪二次热解析分析室内空气中挥发性有机物总量,对样品采集、预处理方式以及仪器工作条件进行实验研究。该方法 16种有机物的线性相关系数均达到0.998以上,其加标回收率范围在73.9%~97.6%,精密度为0.9%~5.9%,10 L采样条件下的方法检出限均低于9μg/m3。对某新居室内空气进行测试,结果可靠,能满足标准要求。

TVOC stands for Total Volatile Organic Compounds, meaning total volatile organic compounds.
Researchers on indoor air quality typically refer to the indoor organic gaseous substances they sample and analyze as VOCs, which stands for Volatile Organic Compound; The various measured VOCs are collectively referred to as Total Volatile Organic Compounds (TVOC).
TVOC is one of the three types of indoor air quality pollution that has a more serious impact. TVOC refers to organic compounds with a saturated vapor pressure exceeding 133.32Pa at room temperature, with a boiling point between 50 ° C and 250 ° C. It exists in the air in an evaporative form at room temperature. Its toxicity, irritability, carcinogenicity, and special odor can affect the skin and mucous membranes, causing acute damage to the human body. The World Health Organization (WHO), National Academy of Sciences/National Research Council (NAS/NRC), and other organizations have consistently emphasized that TVOC is an important class of air pollutants. The definition of VOC by the US Environmental Protection Agency (EPA) is: any carbon containing compound that participates in photochemical reactions in the atmosphere, except for carbon monoxide, carbon dioxide, carbonic acid, metal carbides, carbonates, and ammonium carbonate.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted experimental research on sample collection, pretreatment methods, and instrument working conditions using Tenax composite tube sampling and secondary thermal desorption analysis of volatile organic compounds in indoor air. The linear correlation coefficients of the 16 organic compounds in this method are all above 0.998, with spiked recovery rates ranging from 73.9% to 97.6% and precision from 0.9% to 5.9%. The detection limits of the method under 10 L sampling conditions are all below 9 μ g/m3. The indoor air of a new home was tested and the results were reliable, meeting the standard requirements.
