Fast development and wide application of stripping electroanalytical methods, stripping voltammetry particularly, is due to low detection limit, high sensitivity, selectivity, analysis rapidity, low cost of equipment. Electroanalytical methods provide successful decision of problems connected with environmental and technological processes monitoring, analysis of food, biological and clinical objects, various industrial materials.
Disadvantage of Stripping Voltammetry is the sensor (working electrode). Normally mercury or mercury containing solid electrodes are used as sensors. Basic problem of their application is toxicity of mercury and its soluble salts, necessity of solid electrode surface renewal.
To overcome the difficulties we worked out working electrodes free of mercury or mercury soluble salts.

Advantages of our sensors:

• Environmental safety;
• Electrochemical inertness in wide potential range;
• Electrochemical surface regeneration;
• High sensitivity;
• Great number of determined elements;
• Comfort application in field conditions.
