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.

研制了一种小型、快速、灵敏的挥发性有机化合物（VOCs）连续分析仪，该仪器除可分析沸点100-150℃的挥发性有机化合物外，还可对沸点低于100℃的挥发性有机化合物（VOCs）进行连续分析。正己烷、丙酮、乙酸乙酯、醇类、苯、甲苯、二甲苯等挥发性有机污染物每30 min可连续检测一次，正己烷、乙酸乙酯、苯、甲苯在预富集10 min时的检出限为0.41 μg/m^3（0.12 ppb）、0.67 μg/m^3（0.19 ppb）、0.22 μg/m^3（0.07 ppb）和0.22 μg/m^3（0.06 ppb）。方法的相对标准偏差小于5%。与常规方法相比，本方法对VOCs的灵敏度有较大提高。本文对几个实验室和一个有机废液处理厂的挥发性有机化合物浓度随时间的变化进行了测量，并对挥发性有机化合物的行为进行了分析。挥发性有机化合物的浓度，除了乙酸乙酯，与便携式仪器获得的略低于被动采样器获得的。在本研究过程中开发的便携式仪器可用于化学品的风险评估和管理。
