A simple screening analytical method for determining the emission of volatile organic compounds (VOCs) from household materials was developed using a solid-phase extraction (SPE)-type collection device and a gas sampling bag. The VOCs emitted from the sample material placed in the gas sampling bag with a volume of 20 L were extracted on the SPE-type collection device. In this study, complete sampling mode was developed in addition to a conventional flow sampling mode. The extracted VOCs were then eluted with 8 mL of acetone and measured using gas chromatography-mass spectrometry. The proposed method does not require a stainless-steel chamber and a thermal desorption system; therefore, VOC emission from household materials could be easily evaluated with an affordable cost, suggesting that the method is suitable for the screening technique for evaluating VOC emission from solid materials.
开发了一种简单的筛选分析方法,用于测定家用材料中挥发性有机化合物(VOCs)的排放,该方法使用固相萃取(SPE)型收集装置和气体采样袋。将放置在体积为20 L的气体采样袋中的样品材料所排放的VOCs在SPE型收集装置上进行萃取。在本研究中,除了传统的流动采样模式外,还开发了完全采样模式。然后用8 mL丙酮洗脱萃取的VOCs,并使用气相色谱-质谱联用仪进行测定。该方法不需要不锈钢腔室和热解吸系统;因此,可以以较低的成本轻松评估家用材料中的VOC排放,这表明该方法适用于评估固体材料中VOC排放的筛选技术。
