| Research Abstract |
A small, rapid, and sensitive instrument for the continuous analysis of very volatile organic compounds (VOCs) with a lower boiling point than 100℃ in addition to the analysis of VOCs with a boiling point of 100-150℃ was developed and applied to the measurement of VOCs in the course of university research and environmental monitoring. VOCs, such as n-hexane, acetone, ethyl acetate, alcohols, benzene, toluene, and xylene, can be continuously measured once every 30 min. The detection limits of hexane, ethyl acetate, benzene, and toluene at a pre-concentration time of 10 min were 0.41 μg/m^3 (0.12 ppb), 0.67 μg/m^3 (0.19 ppb), 0.22 μg/m^3 (0.07 ppb), and 0.22 μg/m^3 (0.06 ppb), respectively. The relative standard deviations of VOCs were less than 5%. The sensitivities of VOCs obtained by the present method were higher than those obtained by the conventional method. The temporal changes in the VOC concentrations in several laboratories and at a plant for the disposal of organic liquid wastes were measured, and the behavior of VOCs was analyzed. The VOC concentrations, except for those of ethyl acetate, obtained with the portable instrument were slightly lower than those obtained with a passive sampler. The portable instrument developed in the course of this study may be used for the risk assessment and management of chemicals.
