    摘要: The present invention discloses a corona discharge assembly, an ion mobility spectrometer, an computer program and an computer readable storage medium. The corona discharge assembly includes: an ionization discharge chamber, wherein the ionization discharge chamber includes a metal corona cylinder, and the metal corona cylinder is provided with an inlet of a gas to be analyzed and a trumpet-shaped front port which is conductive to forming a gathered electric field; multiple corona pins, in which on-off of a high voltage can be independently controlled, are installed at the center of the metal corona cylinder in an insulating manner. The present invention further discloses an ion mobility spectrometer using the above-mentioned corona discharge assembly. The present invention can be used to prolong the service life of the integral corona discharge assembly; the discharge voltage of the ion source can be reduced and the discharge stability thereof can be improved; in comparison with the suspended installation of a pin-shaped electrode, since the multiple corona pins are fixed on the PCB, during installation, the position of the electrode can be accurate and stable, thus mass manufacture is easier to achieve.

    摘要: The present disclosure provides an ion migration tube and a method of operation the same. The ion migration tube includes an interior space and an ion gate disposed within the interior space, the interior space includes an ionization region having an absolute value of potential V1 and a migration region. An ion gate is disposed between the ionization region and the migration region and includes a first ion gate grid having an absolute value of potential V2 and a second ion gate grid having an absolute value of potential V3, the migration region comprises at least a first migration region electrode having an absolute value of potential V4 and a second migration region electrode having an absolute value of potential V5. When the ion gate is opened, a potential well is formed for ionized ions between the first ion gate grid and the first migration region electrode so as to compress an ion group entering the migration region.
