Zeta potential measurement cell and zeta potential measurement device

摘要

PROBLEM TO BE SOLVED: To precisely measure a flow of particles by electrophoresis by making an electroosmotic flow as small as possible.;SOLUTION: A zeta potential measurement device includes a substantially columnar housing space S1 which houses a liquid sample, a cell body 21 having a sample introduction path 201 which is open on a side peripheral surface of the housing space S1 and introduces the liquid sample into the housing space S1 from outside, a pair of application electrodes 22 which each have an electrode surface 22A forming a substantially entire axially opposite surface of the housing space S1, and a light introduction part 23 which is formed on a side peripheral surface different from the axially opposite surface of the housing space S1 and introduces light L into the housing space S1, and a light guide-out part 24 which guides the light S having passed through the housing space S1 to the outside.;COPYRIGHT: (C)2014,JPO&INPIT
