生産施設などの大気中の揮発性有機化合物の簡易・迅速評価

It is important to reduce discharge of volatile organic compounds outside, so as to prevent air pollution that related to photochemical smog or suspended particulate matters. In consideration of recent regulation against air pollution, we have independently reduced VOC greatly that has been exhausted outside.
In order to evaluate the VOC reduction appropriately, we studied rapid measuring method of VOC in atmospheric air. As a rapid measuring method of VOC, we selected passive sampler. It has several attractive features relative to the public conventional active sampling method. It is easy to operate without an air pump and a power supply.
The each concentration of VOC element in atmospheric air, for example benzene, was very low. So, good correlation with the conventional public method and high sensitivity were required. Consequently, we confirmed good correlation with them and its sensitivity was sufficient to analyze the low concentration of VOC element.
We found that the passive sampler was applicable to the measurement of VOC in atmospheric air.
