AVA-3 Voltammetry analyzer

The method of the inverse Voltammetric consists in preliminary concentration of the determined elements from the solution to be analysed on the working electrode and following dissolution of the accumulated product and fixation of the analytical signal - voltammetric curve construction.

Application of AVA 

 Sensitivity of element determinatin, μg/dm³

Technical data

Distinctive Features:

• no need to work with metallic mercury because of using solid working electrodes in the device;
• high performances of the working electrode: reliable sealing, simply regenerated working surface of the electrode;
• high operating characteristics of the device;
• no need to work in a room equipped by an exhaust system, no need for gas feed.

Advantages of the Analyzer comparing with devices using other analysis methods (ААS etc.):

• high sensitivity on the basic toxic significant elements (e.g., for Сd, Pb - 0,01 μg/dm³);
• several elements (up to 3) can be determined within one measurement cycle;
• it is possible to determine iodine, organic compounds (vitamin С, В12 and others);
• no need for gas feed, exhaust system;
• low operating costs;
• simple maintenance.

Operation of the Analyzer AVA is fully oriented to a Personal Computer. The Windows software is designed to control the device, measurement and calculation of concentrations.
