Method and apparatus for compressing ions |
| 摘要 |
A method and apparatus for compressing ions inside an ion mobility device is disclosed. Ions are introduced into the mobility device. The ions are subjected to a non-constant electric field to form a potential gradient along a portion of the device so that ions with similar mobilities bunch together into sharper peaks while maintaining separation between other ions. The potential gradient progressively increases or decreases along the length of the device. |

1. A method of compressing ions inside an ion mobility device, comprising:
a. introducing ions into the ion mobility device; b. applying a non-constant electric field to the ion mobility device to form a potential gradient along a portion of the device so that ions with similar mobilities bunch together into sharper peaks while maintaining separation between other ions with different mobilities. |
