| 英文摘要 | a novel membrane inlet interface coupled to a single-photon ionization (spi) miniature time-of-flight mass spectrometer has been developed for on-line rapid measurement of volatile organic compounds (vocs). the vacuum ultraviolet (vuv) light source for spi was a commercial krypton discharge lamp with photon energy of 10.6 ev and photon flux of 10(10) photons/s. the experimental results showed that the sensitivity was 5 times as high as obtained with the traditional membrane inlet. the enrichment efficiency could be adjusted in the range of 10 to 20 times for different vocs when a buffer cell was added to the inlet interface, and the memory effect was effectively eliminated. a detection limit as low as 25 parts-per-billion by volume (ppbv) for benzene has been achieved, with a linear dynamic range of three orders of magnitude. the rise times were 6 s, 10 s and 15 s for benzene, toluene and p-xylene, respectively, and the fall time was only 6 s for all of these compounds. the analytical capacity of this system was demonstrated by the on-line analysis of vocs in single puff mainstream cigarette smoke, in which more than 50 compounds were detected in 2 s. copyright (c) 2007 john wiley & sons, ltd. |
