摘　　要：在自行研制的放电离子源离子迁移谱仪器上,制备了质子化水团簇离子(H+(H2O)n)并研究了丙酮的离子迁移谱。丙酮的产物离子峰个数由浓度决定,当浓度在1 ppb时出现一个产物离子峰,当浓度在几百个ppb时出现两个产物离子峰,当浓度达到1 ppm时出现一个产物离子峰。丙酮在离子迁移谱仪器中发生了质子转移反应生成了单体离子和二聚体离子。实验测量了各种离子的约化迁移率。Reaction ion （ H＋ （H2O）n） is made in a homemade IMS apparatus and ion move spectrometry of acetone is studied. The number of ion peaks, which come from acetone, is depending on their concentration. One ion peak is produced in the lower concentration while two peaks in the high concentration. The products are monotonic cluster ion and dimeric cluster ion can be generated from acetone as proton transfer is occurred in ion IMS apparatus. The reduced mobility can he measured from certain experiment.
