| Abstract: | There is no reactant ion in surface ionization and sample molecules are ionized at the emitter surface.Based on this feature,an ionization source was designed in a form of a plane(the emitter) parallel to a grid(the gate).Molybdenum was used as the emitter material and triethylamine(TEA) as the test compound,the effect of the emitter temperature and the gate voltage pulse width and height on ion mobility spectrum have been investigated.The results indicate that the intensity of ion current is strongly depen... |
