Embodiment Construction

[0031] The application will be described in further detail below in conjunction with the accompanying drawings.

[0032] This application proposes a multi-purpose large-capacity linear ion trap.

[0033] figure 1 Shown is a multi-purpose high-capacity linear ion trap whose RF electrode set consists of two sections, with DC, AC, and RF voltages connected to the pole and end electrodes, respectively, for trapping and analyzing ions. The x electrodes 1, 2 and y electrodes 3, 4 are placed parallel to the z axis, and the RF electrode group is divided into two parts along the z direction, and placed at intervals of 90 degrees in the clockwise direction of 1-3-2-4 in the xy plane, x The electrode pair and the y electrode pair define the ion trapping area of ​​the linear ion trap, and the sub-RF electrode group I and the sub-RF electrode group II correspond to the ion trapping sub-region I and sub-region II respectively. Slits 7 and 8 are provided on the x-electrode pairs of the two...
