| 英文摘要 | an in-source, stretched, hollow fiber membrane (hfm) inlet has been developed to improve the sensitivity of on-line time-of-flight mass spectrometry (tofms) with a vacuum ultraviolet (vuv) lamp based single photon ionization (spi) source for the direct analysis of liquid samples. a 2-cm hfm was stretched to 8 cm in length, and placed in the ion source and directly under the vuv lamp window with a distance of 15 mm. compared with the conventional flow-through configuration under the same experimental conditions, the signal intensities of selected volatile organic compounds (vocs) of methyl tert-butyl ether (mtbe), ethyl tert-butyl ether (etbe), benzene, toluene and p-xylene were increased over 5-fold in magnitude, and the response time was shortened to one-third. the limits of detection (lod) of mtbe, etbe, benzene, toluene and p-xylene ranged from 0.25 to 1.3 mu g l-1 with a measurement time of 60 s, and three orders of linear range were obtained with correlation coefficients of 0.9972-0.9992. the present results suggest that the in-source stretched hfm is a simple and effective way to increase the sensitivity and shorten response time of the membrane inlet, and we believe that it will also be beneficial to other types of on-line mass spectrometer for the on-line analysis of vocs in water with a vuv lamp based spi ion source. |
