Abstract

The invention relates to a pulse field enrichment ion migration tube. The pulse field enrichment ion migration tube is characterized in that high-voltage pulse, which is synchronized to ion gate open pulse, is applied to a pulse electrode set between an ion source and an ion gate, the movement speed of ions is greatly improved during a period of opening the ion gate, and more ions are enabled to pass the ion gate; and meanwhile, spatial focusing is carried out on an ion cluster passed the ion gate by using the difference, which is caused by the high-voltage pulse, in electric field intensity at two sides of the ion gate, and the original resolution of the iron migration tube is maintained.
