MEASURING APPARATUS AND METHOD

摘要

An apparatus and method for measurement are disclosed. The apparatus and method separate solutes and suspended solids in a mixture using a dielectrophoretic force provided by an electrode and a conductive layer, and then perform quantitative or qualitative analysis on at least one of the solutes using the electrode or at least one of the suspended solids.

1. A method for measuring a concentration of a specific substance in a mixture including a plurality of particles, comprising steps of:
providing a single electrode having an initial indicator thereon; causing the mixture to be distributed on the single electrode so that the specific substance reacts with the indicator to cause the indicator to become a changed indicator; providing a dielectrophoretic force acting on the plurality of particles by the single electrode to drive at least a part of the plurality of particles away from a space directly above the single electrode; and obtaining the concentration of the specific substance via the changed indicator.
