项目摘要

Charcoal tubes are widely used for measuring organic vapors in work environments, but it is impossible to know the breakthrough of the vapors during the sampling. In this study, a detection method of organic vapors was developed by using semiconductor gas sensors.Organic vapor was introduced into a glass column equipped with two sensors and the resistance of the sensors was monitored. After the system became steady state, a charcoal tube was attached to upstream of the sensors. The resistance of the sensors was collected temporally to an IC card. The vapor concentration of the exhaust air near the sensors was measured with a FID-gas chromatograph (GC) at intervals of 5 min to obtain the breakthrough curve.When the relative humidity was 0%, output signals of the sensors began to change before the breakthrough was recognized for all of tested organic vapors, that is, acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, methanol, IPA,toluene, 1-butanol, dichloromethane, chloroform and 1,1,1-trichloroethane. When the relative humidity was 80%, the sensors could also be detected the vapor before the breakthrough was recognized for many organic vapors, but the breakthrough of the vapor cannot be detected for dichloromethane and chloroform.Based on the above results, an alarm system that can inform the breakthrough of a sampling device was developed. The developed system can detect the breakthrough of many organic vapors, so that it will become to be useful for an indicator of the sampling limit in charcoal tubes.
炭管是测量工作环境中有机蒸气的常用管,但在采样过程中无法知道蒸气的穿透情况。本研究利用半导体气体传感器建立了一种有机蒸气的检测方法,将有机蒸气通入装有两个传感器的玻璃柱中,监测传感器的电阻。在系统达到稳定状态后,将活性炭管连接到传感器的上游。将传感器的电阻暂时收集到IC卡。当相对湿度为0%时,对于丙酮、甲乙酮、乙酸甲酯、乙酸乙酯、甲醇、IPA、甲苯、正丁醇、丙酮二氯甲烷、氯仿和1,1,1-三氯乙烷。当相对湿度为80%时,对于许多有机蒸气,传感器也能在穿透前检测到蒸气,但对于二氯甲烷和氯仿,传感器不能检测到蒸气的穿透。所开发的系统可以检测到许多有机蒸气的突破,因此它将成为有用的指示器的采样限制在木炭管。
