Abstract

The invention provides an online electrochemical detection device and method and an electrochemical immunoassay instrument. The detection device comprises a separating solution pipeline, and a secondcirculating motor, a third giant magnetoresistance chip module and counter electrodes are sequentially arranged on the separating solution pipeline from front to back; a graphene sensor is arranged onthe wall, opposite to the wall with the counter electrodes, of the separating solution pipeline, and a fifth electromagnet is arranged on the graphene sensor. In the detection device, the graphene sensor is used for performing detection, so that the sensitivity of the detection device is improved; the giant magnetoresistance chip module is used for accurately quantifying immunomagnetic beads, andtest errors possibly caused by loss of the beads in the separation process are compensated for, so that test data is more accurate, the precision of the device is improved, and the detection cost isreduced.

Description

technical field [0001] The invention belongs to the technical field of on-line electrochemical detection, and in particular relates to an on-line electrochemical detection device, method and electrochemical immune analyzer. Background technique [0002] The concentration of antigen / antibody in biological fluid is directly related to its health status, physiological function, physiological cycle, etc. Therefore, quantitative detection of the concentration of antigen / antibody is of great significance to human beings. At present, the antigen / antibody detection technologies in biological fluids mainly include: enzyme-linked immunoassay technology, chemiluminescence immunoassay technology, immunochromatography technology, etc., but these methods have their own advantages and disadvantages. [0003] As a new generation of detection technology, electrochemical immunoassay technology has the characteristics of high sensitivity, good selectivity, and rapid detection, and has shown br...
