Abstract

See full text

The dielectric barrier discharge ionization detector includes: a dielectric tube through which a plasma generation gas is passed; a high-voltage electrode formed on the outer wall of the dielectric tube; two ground electrodes and formed on the outer wall of the dielectric tube, with the high-voltage electrode in between; a voltage supplier for applying AC voltage between the high-voltage electrode and each ground electrode to generate electric discharge within the dielectric tube and thereby generate plasma from the plasma generation gas; and a charge-collecting section for detecting an ion current formed by ionized sample-component gas produced by the plasma. The distance between one ground electrode and the high-voltage electrode is longer than a discharge initiation distance between these two electrodes, while the distance between the other ground electrode and the high-voltage electrode is shorter than the discharge initiation distance between these two electrodes.
