A novel rectangular ion trap apparatus and a method for storing and separating ions. The apparatus comprises a front end cover (11), the front end cover comprising a front end cover left electrode (100), a front end cover intermediate layer insulating body (110) and a front end cover right electrode (120), the front end cover left electrode (100) and the front end cover right electrode (120) being respectively disposed at the left side and the right side of the front end cover intermediate layer insulating body (110), and the central position of the front end cover (11) being hollow; a rear end cover electrode (170), the rear end cover electrode (170) and the front end cover (11) having the same axis, and the central position of the rear end cover electrode (170) being hollow; and a front electrode (130), a rear electrode (140), an upper electrode (150) and a lower electrode (160), wherein the front electrode (130) and the rear electrode (140) as well as the upper electrode (150) and the lower electrode (160) are respectively symmetric about the axis of the front end cover (11), and these electrodes form a spatial area, surrounding the axis, between the front end cover (11) and the rear end cover electrode (170), and used for storing ions. The apparatus can remarkably increase the quantity of ions stored within a unit time. |
