Abstract

The volatile organic compound (VOC) Analyzer is a portable device to measure the four main aromatic hydrocarbon gases: toluene, ethylbenzene, xylene and styrene. With the VOC Analyzer, a semiconductor gas sensor eliminates the need for the carrier gas which is required for conventional gas chromatographs. In addition, since the semiconductor gas sensor is supersensitive to gas components, it is not necessary to use a conventional gas concentrator or other complicated equipment. Compared with other measurement methods, the VOC analyzer is useful for measuring toluene, ethylbenzene, xylene and styrene in wood-based panel because of its ease in obtaining field results and repeating the test. The VOC Analyzer primarily measures four VOC in the air. In this study, we designed a test method of VOC measurement for particle board. A specimen was sealed in 3L polyester bag, after 96hours we could measure maximum VOC emission level that is a stabilized VOC Value. For easy, fast and economic testing of TVOC emission from wood-based panel, we developed the test method with the VOC Analyzer. The VOC Analyzer is expected to gain widespread use in the manufacturing field where a quick and easy test for VOC emission from wood-based panel is required. Furthermore, the VOC Analyzer promises to become an easier, faster and more economic technique than the currently used standard methods.

VOC Analyzer는 톨루엔, 에틸벤젠, 자일렌, 스틸렌 등 4가지 방향족 탄화수소 가스를 측정하기 위한 휴대용 장비이다. VOC Analyzer는 반도체 가스 센서가 존재하는데 이 센서는 가스크로마토그래프에 필요했던 캐리어 가스를 필요 없게 하였다. 게다가 반도체 가스 센서는 가스 성분에 대해 초고감도이기 때문에 전형적인 가스 포집기나 복잡한 장비가 필요 없다. 다른 측정방법과 비교하면 VOC Analyzer는 실험의 반복과 결과의 도출이 용이하기 때문에 건축자재에서 톨루엔, 에틸벤젠, 자이렌, 스티렌을 측정하는데 유용하다. VOC Analyzer는 기본적 공기 중의 4가지 VOC를 측정하는 것인데, 본 연구에서 재료, 파티클보드에서 방산되는 VOC를 분석하는 방법을 고안하였다. 시편을 밀봉하여 96시간 후에 측정할 때 최대 VOC 값, 즉 안정화 된 VOC 방산량을 측정할 수 있다. 건축자재의 TVOC 방산을 측정 시 다른 방법에 비해 쉽고, 빠르며 경제적인 시험 방법이라 VOC Analyzer를 이용한 시험 방법을 개발하였다. VOC Analyzer는 건축 자재로부터 방산되는 VOC에 대해 빠른 측정과 쉬운 시험방법이 요구되는 곳에 널이 사용 될 것이라 기대한다. 더욱이 VOC Analyzer는 현재에 사용되고 있는 표준 방법 보다 더 쉽고, 빠르고, 경제적인 기술로의 적용이 가능하였다.
