Example Embodiment
[0029] Example 1
[0030] The schematic diagram of the two-dimensional array of the array type ion transfer tube of the present invention is as figure 1 Shown.
[0031] An array type ion migration tube, which includes an ionization source area 2, a reaction area 3, an ion gate 4, a drift area 5, a grid 6, and a Faraday disk 7 along an axis from left to right;
[0032] The drift zone 5 is a cylindrical space structure formed by alternately superimposing an insulating ring and an electrode ring 8; along the axial direction of the cylindrical space structure, an ion gate 4 and two parallel to each other are sequentially arranged at one end of the drift zone 5 An ionization source area 2 is provided between the ion gate 4 and the ionization source area 2 with an insulating ring and an electrode ring, and a cylindrical space structure inside the insulating ring and the electrode ring is used as the reaction area 3; in the reaction area near the ion gate 4 An air outlet is provided on the...
Example Embodiment
[0042] Example 2
[0043] An array type ion migration tube, which includes an ionization source area, a reaction area, an ion gate, a drift area, a grid, and a Faraday disk along an axis from left to right. The difference from Embodiment 1 is that the ionization source area There are three Faraday disks and three ionization source regions or Faraday disks respectively. The ionization source regions or Faraday disks are parallel to each other, and the ionization source regions and Faraday disks are in one-to-one correspondence with the two ends of the axis of the migration tube, forming three or more migration tubes. Detection channel.
