摘要
The present invention provides dielectric barrier discharge ionization, including a dielectric barrier discharge tube and an electrode pair consisting of a first electrode and a second electrode. At least a portion of the dielectric barrier discharge tube is provided between the first electrode and the second electrode.The electrode pair can ionize the sample after the power is turned on. The dielectric barrier discharge tube is in communication with a vacuum portion.The pressure range in the dielectric barrier discharge tube is 0.01 to 100Pa. The dielectric barrier discharge ionization provided by the invention remedies the defects of existing low-pressure ion sources in the pressure range, and provides the low-pressure ion source with high ionization ability, high versatility and simple devices.
