Zeta-potential measurement cell and zeta-potential measurement equipment

摘要

P To precisely measure a flow of particles by a cataphoresis by reducing an electroosmosis flow as much as possible. PSOLUTION: A zeta potential measurement cell includes: a storage space S1 nearly in a columnar shape for storing a liquid sample; a cell body 21 including a sample introduction passage 201 which is open to a side peripheral face of the storage space S1 and introduces the liquid sample from the outside to the storage space S1; a pair of application electrodes 22 including an electrode surface 22A for forming a nearly entire surface of an opposing axial surface of the storage space S1; and a light introduction part 23 for introducing light L into the storage space S1 and a light leading part 24 for leading light S through the storage space S1 to the outside.
