Problems solved by technology

Most of the pipe cross-sections of existing microfluidic chips use square cross-sections, the inertial separation efficiency is not high, and it has a certain impact on the detection accuracy; while the normal use of 12-electrode detection tends to cause too much measurement data, which affects the detection efficiency

Abstract

The invention discloses an inertial separation microfluidic chip based on electrical impedance tomography (EIT) visual detection. The microfluidic chip is composed of a tube, a first electrode array set, a second electrode array set, and a third electrode array set. The first electrode array set is arranged in the inlet of the tube. The second electrode array set is arranged in the middle bend ofthe tube. The third electrode array set is arranged in the outlet of the tube. The electrodes of the first electrode array set, the second electrode array set, and the third electrode array set are all connected to a pin socket. The provided microfluidic chip has a simple structure, is suitable for detecting a high concentration solution, and is non-invasive. The pipeline is in a round shape, andthus has a higher detection precision, compared with a square pipeline.

Description

Technical field: [0001] The invention relates to an inertial separation microfluidic chip based on visual detection of electrical impedance imaging, which belongs to the field of analysis and testing. Background technique: [0002] The inertial separation microfluidic chip is a device based on electrical impedance imaging technology, which uses its own structural characteristics to realize the inertial separation of solutions and image the process. It is widely used in medical testing and industrial testing. Most of the existing microfluidic chips use square cross-sections for the pipe cross-sections. The inertial separation efficiency is not high, and it has a certain impact on the detection accuracy; while the normal use of 12-electrode detection tends to cause too much measurement data, which affects the detection efficiency. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] The present ...
