| 英文摘要 | a home-made miniature orthogonal acceleration time of flight mass spectrometer with vacuum ultraviolet vuv photolonization source has been designed and tested. the vuv lamp with photon energy 10.5 ev is a soft ionization source to form only parent ion without fragmentation for most organic compounds which makes the mass spectrum of a mixtures can be identified without prior separation. the orthogonal acceleration structure can improve resolution obviously in a short field free mass analyzer. resolution of 430 has been achieved in a orthogonalacceleration linear configuration with a 32-cm field free flight path for methyl iodide. the total analysis time. is 20 s at the rate of 10 khz for, mass. spectra recording, and detection limits of 10 x 10(-6)(v/v) and 5 x 10(-6) (v/v) were measured for benzene and methyl iodide respectrvely. the combination of soft ionization and orthogonal acceleration makes the spectrometer portable and. has a wide application in real-time and on-line monitoring of volatile organic compounds. |
