Analysis method of insulating particles using electrochemical analysis in high concentration redox active electrolyte solution

摘要

The present invention relates to an analysis method using electrochemical analysis, and more particularly, to a method comprising: injecting insulating particles into a reaction solution of an electrochemical cell containing a redox mediator; and an electrochemical analysis method and a reactor comprising the step of measuring a change in current of the electrochemical cell; and a reaction solution; wherein the reactor includes a counter electrode, a reference electrode, and a working electrode having a maximum diagonal length of 1 to 500 μm on the electrode surface, and the reaction solution contains a redox species, , It is characterized in that at least one selected from the group consisting of size, velocity, attractive force, and charge analysis of the insulating particles is measured through the change in the intensity of the current generated when the insulating particles in the reactor collide or adsorb to the surface of the working electrode. An electrochemical analysis kit is provided. When insulating particles are analyzed through the analysis method and analysis kit of the present invention, the measurement sensitivity can be more remarkably increased, and the measurement accuracy of the size of the insulating particles, the access speed to the electrode, the attractive force with the electrode, and the particle surface charge can be improved. can
