Particle characterization cell and particle characterization instrument

摘要

The present invention is configured to be provided with: a bottom-equipped tubular cell main body 21 that forms an internal space S1 that extends in a longer direction, and has one end part 21x that is opened; a pair of applying electrodes 22 that are arranged so as to face to each other in the internal space S1; and a fixing spacer 23 that intervenes between the pair of applying electrodes 22 to thereby define a distance between the applying electrodes 22, and fixes the pair of applying electrodes 22, wherein in a state where the fixing spacer 23 is inserted into the cell main body 21, in a lower part of the internal space S1 of the cell main body 21, a zeta potential measuring space S2 in which the pair of applying electrodes 22 are exposed is formed.
