Sampling bag-based emission chamber for measuring volatile organic compounds from household materials using solid-phase extraction-type collection device.

Abstract

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 8mL 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.
