The Twentieth International Symposium on Electroanalytical Chemistry (20th ISEAC) will be held in Changchun, China, August 12-15, 2025. Since 1987 the First ISEAC was held under the auspices of the Chinese Chemical Society (CCS) and the Chinese Academy of Sciences (CAS), it has been held regularly every two years in Changchun, the beautiful city in the Northeast of China. The aim of the symposium is to provide a forum open to all electroanalytical chemists in the world to discuss their recent findings and information, and exchange their mutual interests or a broad area of electroanalytical chemistry for possible cooperation and to promote international friendship.

It is always organized on behalf of the CAS mainly by the Open Laboratory of Electroanalytical Chemistry (LEAC) in the Changchun Institute of Applied Chemistry (CIAC) of the CAS. The LEAC has been promoted to the State Key Laboratory of Electroanalytical Chemistry (SKLEAC) in 2001.

The symposium intends to emphasize the important recent development in electroanalytical chemistry including theories, methods and applications and to encourage us to proceed to new fields especially the multidisciplinary fields. Many stimulating discussion and suggestions are expected during the symposium. The symposium will include plenary, invited and oral lectures as well as poster presentations. 

All electrochemists and electroanalytical chemists are warmly welcome to participate in the symposium and visit our SKLEAC < http://www.skleac.ciac.cas.cn/2020gbsy/>.
