Round-robin tests were conducted in order to investigate a simple and easy method for preparing a standard gas mixture of volatile organic hazardous air pollutants from their mixed solution by 16 members of the Association for Environmental Analysis in Osaka. Seven compounds (acrylonitrile, dichloromethane, chloroform, 1, 2-dichloroethane, benzene, trichloroethylene, and tetrachloroethylene) were accurately weighed into a vial one by one. An aliquot of this liquid mixture was transferred into a glass vessel (1 or 21) using a microsyringe, and then vaporized. The resulting gas mixtures (about 300 ppm each) were evaluated as a first standard gas by gas chromatography. The obtained results prove this method to be accurate and precise for the preparation of a standard gas mixture.
