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.
