| 摘 要： | 以<大气污染物综合排放标准>(GB 16297-1996)中有机物的实时在线测量为目的.对自行研制的质子转移反应质谱(proton transfer reaction mass spectrometry,PTR-MS)装置的参数进行了优化和测量.利用高纯N2稀释的单一有机物PTR-MS测量结果表明,在E/N=144 Td条件下,质子化的有机物离子为主要的产物离子峰,没有明显的碎片离子存在.测试了进样系统中催化转化装置的性能,给出了11种挥发性有机物的探测灵敏度和检测下限,讨论了PTR-MS的测量精度.测试结果表明,自行研制的PTR-MS能够实时在线监测<大气污染物综合排放标准>中规定的有机污染物.

| Abstract: | Parameters of homemade proton transfer reaction mass spectrometry(PTR-MS)for on-line mea- surements of volatile organic compounds(VOCs)restricted inIntegrated Emission Standard of Air Pollu- tants(GB 16297-1996)were optimized and measured.The individual VOCs in pure N_2 were measured at E/N=144 Td by PTR-MS and the results show that the main ions are the protonated compound and few fragmentations exist.The sensitivity arid limitation of homemade PTR-MS was obtained to 11 VOCs.The efficiency of the catalytic... |
