Abstract

See full text

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.
