Method and apparatus for aerodynamic ion focusing |
摘要 |
A method and apparatus for focusing ions for delivery to an ion detection device using an aerodynamic ion focusing system that uses a high-velocity converging gas flow at an entrance aperture to focus an ion plume by reducing spreading and increasing desolvation of ions, and wherein a voltage is applied to at least a portion of the aerodynamic ion focusing system to assist in the focusing and delivery of ions to the ion detection device.
