Discharge Ionization Current Detector

A low-frequency high AC voltage from an excitation voltage power source (14) is applied between one electrode (8) and two other electrodes (9A and 9B) to generate a low-frequency AC-excited dielectric barrier discharge within a gas passage (3), thereby creating atmospheric pressure non-equilibrium micro-plasma. A sample gas is mixed with hydrogen inside the passage of a nozzle (51), and further mixed with air outside an exit port (53) to burn, forming a hydrogen flame (57). Then, the sample gas reaches an ionization area (56), where the sample components are ionized due to the effect of light emitted from the plasma. Meanwhile, water molecules generated in the hydrogen flame (57) are supplied into the ionization area (56), whereby some of the sample-molecule ions are hydrated while the others undergo a reaction to form a hydroxonium ion. These kinds of hydrated ions have long lifetimes and barely become extinct halfway, so that they can efficiently reach a detection electrode (13) and be detected as ion current. As a result, the detection sensitivity is improved and the dynamic range is enhanced.
