In order to study the roles of ions in nucleation and gas-phase chemical reactions, it is necessary to generate ions with uniform electrical mobility at a high concentration and to measure them without significant losses of ions. In the present work, we studied the performance of a newly developed ion mobility analyzer which separates ions in axial direction of gas flow. The experimental results showed that measured ions' electrical mobility distribution is not influenced by the flow rate of carrier gas and that the average mobilities of positive and negative ions are respectively 1.6 × 10-4 and 1.9 × 10-4 m2V-1s-1. Although classification characteristics of the analyzer measured by DMA-classified NaCl particles (2.5 ∼ 8 nm) was not sharp enough to obtain ions in a narrow mobility range, the ion classifier was able to distinguish ions generated in He from those in Air and N2. Further modification of the analyzer to improve classification characteristics was proposed.
