| 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%)。

| Abstract: | With a focus on the increasingly serious environmental pollution, the thesis introduces the Vehicle-mounted Combined TD-GC-MS (Gas Chromatography-Mass Spectrometer-Thermal Desorption) System (including a positive pressure system) and studies on the application of the system in detecting malodorous substances(organic sulfur ). As the study result shows, the system helps solve a common problem in detecting malodorous substances(organic sulfur ), i.e., the existing emergency equipment can only be applied to semiquantitative detection; it can also avoid the disturbance or losses in the process of transporting samples to laboratories. Its detection limit is between 8 and 14 ng and the degree of precision is between 3.7% and 4.1%. |
