Anwendungsbeispiel aus der Fahrzeugtechnik,mposition of the sprayed droplets. The most noteworthy result is the low mobility of the final positive ion (about 0.95 × 10. m./Vs) compared to that of the negative ion (about 1.77 × 10. m./Vs). The mass differences which this implies are discussed..In a supplementary experiment it was shown that aCommemorate 发表于 2025-3-25 21:02:54

The air is irradiated by ionization source (.Po, 0.1 mCi) for obtaining charge equilibrium before introduction into both tubes..Before passing through the ion denuder, the charged fraction of particles with radiu欢呼 发表于 2025-3-26 09:39:38

The processes of charge exchange, ion clustering and proton transfer are found to convert ions of primary air species into those characteristic of trace constituents in the mixture. For these measurements we have used a drift cell-mass spectrometer combination to mass analyze ion慎重 发表于 2025-3-26 17:58:09
