Abstract: Provided is an ionizer. In an embodiment, concaves-convexes are formed on a surface of a substrate, one or more electrodes for generating a positive ion or a negative ion is formed, and the concaves-convexes are coated with photocatalyst. The electrode is formed on a surface opposite to the surface on which the concaves-convexes are formed, and two or more substrates are disposed in line at an interval while the electrode and the concave-convex face each other. One or more pillar planes forming a polygonal pillar in which polygonal planes facing each other are perforated form the substrate, the one or more electrodes are formed on at least one inner surface of the pillar planes, and the pillar plane forming the substrate faces the pillar plane the electrode. The pillar plane forming the substrate and the pillar plane the electrode are alternately disposed.

Abstract: The present invention relates to a dust measurement device and method which can increase the accuracy of dust measurement by deriving a mass concentration on the basis of a number concentration distribution according to particle sizes. The dust measurement device of the present invention comprises: a charging unit for charging a feed material with electrical charges; a first dust collecting unit including a first and a second dust collecting electrode which are spaced apart from each other, through which the material passes, and to which different voltages are applied; a second dust collecting unit for collecting the material which has passed through the first dust collecting unit; a current measurement unit for measuring current flowing through the second dust collecting unit; and a control unit for calculating a mass concentration of the material by using the value of the current measured by the current measurement unit and adjusting voltages applied to the charging unit and the first dust collecting unit on the basis of the mass concentration.
