A sampling nozzle (21) is connected to one end, an ion supplying tube (31) continuing to an analysis device (50) is connected to another end and a barrier discharge tube (11) is connected to still another end of a T-shaped tube (41) which has three connecting ports, and an ionization chamber (SP) is positioned in the center of the T-shaped tube (41). The ionization chamber (SP) defines a closed space, and the ions generated herein are introduced into the analysis device (50) via the ion supplying tube (31). Thus, almost all the ions are introduced into the inside of the analysis device. |
