Abstract

This study was carried out to evaluate the performance of a small chamber sampling and analytical method for the measurement of total volatile organic compounds (TVOC) and formaldehyde (HCHO) emission from building materials. While VOC was determined by the adsorbent tube sampling and sequential thermal desorption coupled with GC/MSD analysis, formaldehyde sampled with DNPH-silica cartridge was analyzed by HPLC. Wide-range performance criteria such as repeatability, desorption efficiency, emission chamber recovery test, duplicate precision, breakthrough volume and method detection limits were investigated for the evaluation of small chamber method. The overall precision of the small chamber sampling and analytical methods was estimated within 20~30% for target compounds. In conclusion, this study demonstrated that the small chamber sampling and analytical method can be reliably applied for the measurement of building materials pollutants.

최근 들어 실내공기질 악화의 주 오염원인 건축자재에 대한 관심이 고조되면서 건축자재 오염물질 방출시험 자료 구축이 중요하게 됨에 따라, 신뢰성 있는 자료 확보를 위해 건축자재 방출시험 정도 관리에 대한 필요성이 대두되었다. 이에 본 연구는 건축자재 방출시험 성능에 대한 정도관리를 위해 총 휘발성 유기화합물과 포름알데히드에 대하여 기기분석 재현성, 회수율, 검출한계, 중복 및 반복채취 재현성, 파과용량 평가 등을 실시하였다. 기기분석 및 시료채취에 대한 재현성은 20~30% 이내의 양호한 결과를 보였으며, 회수율은 80% 이상으로 나타났으며, 파과 역시 일어나지 않아 소형챔버법에 의한 성능은 전반적으로 만족할 만한 수준을 보였다. 따라서, 소형챔버를 이용한 건축자재 오염물질 방출시험방법은 신뢰성있는 자료를 제공해 줄 수 있을 것으로 판단된다.
