摘要： To widen the dynamic range of a dielectric barrier ionization detector (BID), an insertion length of a sample injection tube 16 into a second gas passage 11 is set so that a sample-gas ejection port 16a is located on the downstream side of a dilution gas from the upper edge of a collector electrode 14 at which a DC electric field concentrates. By this setting, although the detection sensitivity is lower than in the case where the sample-gas ejection port 16a is placed to maximize the detection sensitivity, the decrease in the detection sensitivity to high-concentration samples is reduced since absorption of light by the sample gas is alleviated. Consequently, the sample-concentration range with a linearly-changing sensitivity becomes wider than that of conventional BIDs. Although the detection sensitivity becomes lower than that of conventional BIDs, a detection sensitivity adequately higher than that of FIDs can be ensured.

摘要： Provided is a discharge ionization current detector that is highly durable and yet can be produced at a low cost. An electrode structure 19 consisting of a dielectric-coated metal tube 16, with an insulator-coated metal wire 18 included therein, is inserted from above into a first gas passage including a dielectric tube 10. The metal tube 16 is connected to the ground on the upstream side of the first gas passage. One end of the metal wire 18 is extracted from the upstream side of the first gas passage to the outside and connected to a bias power source 33. An area which is not covered with the insulator is provided at the other end of the wire 18. This area is arranged in a second gas passage, which extends from the downstream end of the first gas passage. A metal electrode consisting of a flanged metal tube 28 is placed in the second gas passage and connected to an ion current detecting circuit 34. In the present configuration, the second gas passage, which should be heated to high temperatures, has fewer portions at which metallic parts are in contact with insulating members. This is advantageous for improving the durability of the device and reducing the used amount of expensive, highly heat-resistant sealing members and/or insulating members.
