CORONA DISCHARGE COMPONENT AND METHOD FOR PERFORMING CORONA DISCHARGE

摘要

A kind of corona discharge component and the ionic migration spectrometer using the corona discharge component. The corona discharge component includes: ionic discharge chamber, the ionic discharge chamber includes metal corona cylinder (314), which has gas access to be analyzed and form the centre round-meshed ring plate shape port of non-uniform electric field with corona pin (305); A rotary shaft is insulated on the barrel of the metal corona cylinder (314), for the rotary shaft perpendicular to the axis of the metal corona cylinder (314), which is equipped with the turntable for there are more corona pins (305) in outer marginal zone. Improve the service life of whole corona discharge component; The discharge voltage for reducing ion source, improves its discharge stability; Relative to the hanging installation of needle electrode, more corona pins (305) are due to being fixed on pcb board (301), and when installation can accomplish the precise and stable of electrode position, to be easier to batch micro operations.
