Development of a passive flux sampler (PFS)

The mitigation to reduce indoor pollutant concentration are increasing ventilation rate or to reduce the emission of the pollutant which is also common in VOCs. Households, furnitures, building materials and so are well known as the source of indoor VOCs. There are several devices to measure emission of VOCs, such as an emission chamber or FLEC, which are adopted in ISO 16000. However these 2 methods has each disadvantages e.g. the chamber is suitable only in a fixed condition such as a laboratory, or the necessity of a pump and humidifer. The device introduced in this study is portable (D x H = 41 x 16(mm)) and samples VOCs only by diffusion so there is no necessity of pump. The size of the sampler, adsorbent, detection limit, the sampling period, reproductivity, and the possibility of practice will be discussed in this study.
