Abstract
A BID includes: a discharger () including a dielectric pipe () and a pair of electrodes () attached on an outer wall of the dielectric pipe, the pair of electrodes () being arranged at a distance from each other in a direction along a central axis of the dielectric pipe (), the discharger () being arranged so that plasma generating gas is introduced from a first end of the dielectric pipe () and configured to generates dielectric barrier discharge inside the dielectric pipe () to generate plasma; a detection section () including a sample gas introduction section () and a collection electrode () for collecting ions, the detection section () being configured to ionize components in the sample gas using light emitted from the plasma generated in the discharger () and to detect the generated ions by collecting them using the collection electrode (); and a voltage supply (') for generating a potential difference between the pair of electrodes ().
