Electrochemiluminescence analysis system integrates electrochemistry and luminescence analysis into a whole, which is convenient to use and easy to control accurately, ensuring that the determination results of electrochemiluminescence analysis are more accurate and stable, and greatly improving the sensitivity of determination. Especially for the determination of trace substances, it has more advantages. Application fields: detection and analysis of drugs, amino acids, polypeptides, proteins and nucleic acids, research on the interaction between proteins and drugs and nucleic acids, and analysis and determination of trace substances in the fields of environment, ecology and food hygiene.
