Recently, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences has made great achievements in the research and development of electrochemical analytical instruments and combined technologies.

Series of achievements, self-developed rapid biochemical oxygen demand detector, micro electrochemical system, electrochemical in-situ membrane conductivity measurement

Instrument and electrochemical in-situ surface plasmon resonance analyzer have high sensitivity, fast response and long service life.

Long, dynamic online detection, its main performance indicators have reached the international advanced level, and filled a number of domestic and foreign space in this field.

White.

Electrochemical method, as a simple, rapid, accurate and highly sensitive analytical detection and characterization method, is widely used in scientific research and production.

It occupies a more important position. Electrochemical analytical instruments have been widely used in analytical laboratories. But at present, domestic analytical instruments, especially high

A large share of sophisticated analytical instruments still depends on imports, and some urgently needed special instruments are still blank. Therefore, further development has our own knowledge.

New electrochemical sensors, detectors and functional interface instruments with intellectual property rights are the urgent needs of current scientific and technological production.

The researchers of the State Key Laboratory of Electro-analytical Chemistry of Changchun Yinghua Institute started from the actual needs of production and scientific research, based on the frontier field, and worked in

In 2005, he undertook the scientific and technological development plan project of Jilin Provincial Science and Technology Department "Research and development of electrochemical analytical instruments and combined technology". They study

Develop new electrochemical sensors, detectors and electrochemistry with fast, real-time, sensitive, automatic and continuous detection, economic application and independent intellectual property rights.

Aiming at the combined equipment, focusing on the design method of electrochemical instruments, highlighting the characteristics of miniaturization and high performance, the combined research of electrochemical methods is carried out.

Focusing on the application fields of environmental monitoring, electrochemical analysis of materials, biological analysis, etc., it is oriented to biochemical oxygen demand, in-situ membrane conductivity measurement and surface plasma separation.

Daughter resonance measurement, developed four kinds of electrochemical and electrochemistry combined instruments and equipment.

The biochemical oxygen demand (BOD) was achieved by using a new type of organic-inorganic hybrid membrane immobilization material and field cultivation of microorganisms.

Rapid detection, this innovative method shortens the traditional BOD detection time from 5-7 days to about 1 hour, and develops a rapid BOD detection based on this.

The instrument has realized the miniaturization design of electrochemical analysis instrument, and the micro USB2.0 connected with C] electrochemical system has been developed, which can improve the accuracy and data of potential control.

The main indexes such as transmission speed are much higher than those of the previous instruments, but the volume is only the size of a finger, which is 2~3 orders of magnitude smaller than that of the traditional instruments.

It can be easily integrated into various analytical instruments, and realize the combination of various analytical methods and electrochemical methods, which has good expansibility and is suitable for the field.

External and various on-site use; The in-situ real-time monitoring of the conductivity of thin film materials is realized by using a self-designed double-band electrode with a small gap, and

An electrochemical in-situ membrane conductivity measuring instrument with high time-resolved measurement ability was developed, which can be used for dynamic measurement of membrane conductivity change.

Self-designed displacement sensor improves the time resolution of surface plasmon resonance spectroscopy (SPR) measurement, and on this basis, electrochemical and electrochemical methods are used.

The surface plasmon resonance spectrometer for electrochemistry is developed by integrating chemical methods, and the SPR signals of steady and transient electrochemical systems are realized

Measurement of.

The successful research and development of these four kinds of electrochemical related instruments enriches the research methods of basic science and can be widely used in environmental detection and social security.

And scientific research and other fields. At the same time, it can meet the requirements of mass production of industrial design and commercialization, and has wide application value.

And has broad market prospects.
