Modern home decoration caused by indoor air pollution has attracted increasing attention, and volatile organic matter is an important indoor air quality pollution factors. According to WHO, the organic compounds with boiling points between 50 ° C and 260 ° C are called Volatile Orgic Compounds and Total Volatile Organic Compounds (TVOC), the total mass of volatile organic compounds in air.

    Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., the use of ultra-high sensitivity gas chromatography to detect indoor air total volatile organic compounds, the establishment of benzene, toluene, butyl acetate, ethylbenzene, p-xylene, The correlation coefficient R2 of each component is 0.999 2 ~ 1. The reproducibility of the method is investigated. The RSD of the 6 parallel tests is 0.8% ~ 1.4%.
