英文摘要: A single photon ionization time of flight mass spectrometer with membrane inlet has been described and applied for on-line measuring volatile organic compounds (VOCs) in water. Automatic sampling, enrichment and measurement of VOCs were achieved by using a polyolimethyl siloxane (PDMS) membrane with a thickness of 50 mu m, a peristaltic pump and electric switch valve. There is almost no memory effect in the membrane inlet system. Single photon ionization processes were accomplished with photons of 10.6 eV emitted from a commercial low pressure discharge krypton lamp, and almost no free fragment was found in mass spectrum. Thus, it can be used for chemical compounds identification according to their molecular weight. The response times for benzene, toluene, xylene and chlorobenzene were all shorter than 100 s. The detection limit of benzene is 3 x 10(-9) (volume fraction), and an excellent linear response was observed in the range of 10 x 10(-9) (V/V) to 1 x 10(-6) (WV). The instrument was tested to analyze VOCs in the sewerage from a chemical plant, and more than twenty compounds of VOCs with concentration in 10 x 10(-9) (V/V) level were observed in 200 s. The results indicate that the single photon time-of-flight mass spectrometer with membrane inlet has a great application potential for on-line analyzing VOCs in water.
