In this paper the effect of water vapor on resolving power of ions in Ion Mobility Spectrometer (IMS) has been investigated. First of all the primary peak of reactant ions (RIP) generated by corona discharge ionization source in IMS system was recorded without reagent gas, then by inserting acetone as reagent gas, moisture has been eliminated by chemical reactions between acetone and water, and again resulting peak has been recorded and compared with previous one. It was observed that the second peak width is much thicker and subsequently has better resolving power than the first one.
Keywords: : ion mobility spectrometry, reagent gas, resolving power.
