摘要： An ionization device includes an ionization chamber (1) and a charging chamber (20) separately prepared therefrom. The ionization chamber (1) has a discharge electrode (6) and an opposing electrode (10) in an interior (4) of a case having an ionizing gas introducing inlet (14). The opposing electrode (10) has an orifice (8) communicating with outside and formed at a position opposing the tip end of the discharge electrode (6). The charging chamber (20) is arranged adjacent to the orifice (8) side of the ionization chamber (1). An introduction inlet (28) of a charge object introduction portion of the charging chamber (20) is arranged at the position near the exit of the orifice (8). The size of the orifice (8) is set so that the charge object is sucked therein by a negative pressure generated when a gas containing ions is sprayed from the exit of the orifice (8) into the charging chamber (20) and the ionization chamber (1) has a higher pressure than the charging chamber (20).

摘要： A classification apparatus for classifying and separating particles having particle sizes within a predetermined range is disclosed. In a preferred embodiment of the classification apparatus, a center electrode (3) and an outside electrode (4) generate an electric field for classifying charged fine particles according to electric mobility. In the upper part of a housing (1), a sheath gas supply portion (7) is provided. An aerosol supply portion (11) has an introduction port (11a) provided on the outside electrode (4) side in a classification region (5), and supplies a charged aerosol at a constant flow rate through the introduction port (11a). On the downstream side in the flow of a sheath gas in the classification region (5), a larger-size particle discharge portion (13) is provided. The larger-size particle discharge portion (13) has a discharge port (13a) provided on the outside electrode (4) side, and discharges charged fine particles, which are contained in the classified charged aerosol and have particle sizes larger than a predetermined particle size, together with part of the sheath gas at a constant flow rate. A detector (18) is provided downstream of the housing (1) to detect the number of remaining charged fine particles contained in the sheath gas introduced thereinto as the quantity of electricity.
