Abstract
A discharge ionization current detector of the present invention is used for a detector for a gas chromatograph and suitable for analyzing high-boiling components. A discharge ionization current detectoris mainly constituted by a plasma generating sectionand an ion collecting section. Regarding the ion collecting section, an ion collecting electrodeand a bias electrodeare arranged, and furthermore, an insulating member made of sapphire or aluminum oxide having a purity equal to or greater than 99.5% is arranged between the ion collecting electrodeand the bias electrode
