| 中文摘要: |
| 为了应对当今日益突出的环境污染问题,介绍了一套车载色质-热脱附联用系统(配有正压系统),并研究该系统在恶臭类物质(有机硫)测定方面的应用,结果发现该车载式色质-热脱附联用系统在恶臭物质测定方面即能解决目前应急设备所普遍存在只能半定量的问题,又能解决样品送到实验室分析时,运输过程所带来的干扰、损失。其检出限在8-14ng,精密度在3.7-4.1%范围内。 |
| 英文摘要: |
| 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%. |
