Abstract
Recently, the health hazard by chemical substance such as the Sick House Syndrome has been watching all over the world. It has been required that exhalation of the volatile organic compounds such as toluene and xylene has to be reduced and eliminated from the hardened coating film. A ‘small chamber method’ has been prescribed in Japanese Industrial Standards as a method that quantitatively determines exhaled the volatile organic compounds from the hardened coating film. In this paper, a headspacebial method which can easily analyze the traces of the volatile compounds from the coating film and corresponds to a result of the small chamber method is discussed.
