摘要：

The problem of hazardous industrial chemicals ions separation with close mobility by IMS method has identified the need of design and drift tube electrical parameters modeling to ensure the ion transport. A simulation of IMS drift tube electric field was performed and the trajectories of the ions in the region of ionization source electrodes, in the ionization region and in the drift region of IMS tube was shown. Obtained results have allowed to estimate influence of inhomogeneity of the field in the drift region on the resolution of the ion mobility spectrometer, as well as to make changes in the parameters of the tube to minimize this impact. Based on the performed modeling have been identified best constructive decisions for the manufacture of drift tubes. On the manufactured drift tube been successfully carried out the experimental detection of hazardous industrial chemicals. (C) 2014 Published by Elsevier Ltd.
