Abstract

Disclosed is a hybrid ion guide which combines the advantages of the conventional electrostatic ion guide and the RF ion guide, comprising an electrostatic ion guide for transmitting the injected ions and applying a voltage for the ions to be focused upon the center axis of the ion transmission direction, and an RF ion guide which is connected to the electrostatic ion guide and passes the ions focused upon the center of the axis of the ion transmission direction. From the constitution of the hybrid ion guide, ion transmission efficiency can be improved.
