摘　　要：为了应对当今日益突出的环境污染问题,建立了一套车载色质-热脱附联用系统（配有正压系统）及其对恶臭类物质测定的方法。该系统在恶臭物质测定方面既能解决目前应急监测设备所普遍存在的只能半定量的问题,又能解决样品运送到实验室分析过程中所带来的干扰、损失的问题。方法检出限在8~14ng/m3,精密度好（RSD小于4.1%）。With a focus on the increasingly serious environmental pollution,a vehicle-mounted combined TDGC-MS System（ including a positive pressure system） was established and carried out to analyze malodorous substances（ organic sulfur）. The results showed that the established system not only solves the problem in analyzing malodorous substances（ organic sulfur）,i. e.,the existing emergency monitoring equipment can only be applied to semi-quantitative detection; it can also avoid the disturbance or losses produced during the transporting process of samples to laboratories. The detection limits of the system are in the range of 8 ~ 14 ng / m3. It possesses a good analytical precision with RSD within 4. 1%.
