The instrument series AVA is designed to measure mass concentrations of toxic elements (Cd, Pb, As, Hg, Zn, Cu, Tl etc.) at the maximum permitted level and lower. The scope of the application covers the following subjects: water, air, soil, food products, biological substances, medical drugs and other objects. 

The AVA analyzers use the electrochemical method of stripping voltammetry with the working solid carbon electrode with linear sweep trace. The price of the AVA instrument in standard configuration. Our specialists are ready to make a configuration that will suit your specific analytical tasks. 

AVA analyzers are designed to:

• Define the contamination with toxic metals at the level of maximum permitted level and lower in food products, alcoholic & non-alcoholic drinks, foodstuff, medical drugs, drinking and natural water, air in living areas and working zones, fertilizers, cosmetics, toys, tableware etc;
• Certification of foodstuffs & fodder;
• Safety control;
• Monitor the ecological environmental objects (natural, fresh & sea water, purified sewage, air of populated areas & industrial zones, soil, sift & bottom sediments)
• Clinical tests of biological objects (blood, urine etc.);
• Analyse the composition of geological rocks & minerals; 
• Control the technical processes in the manufacturers.

Scope of application:

• Ecology and environmental protection;
• Food production industry;
• Health and epidemiological monitoring;
• Medicine and pharmacology;
• Tox screen;
• Geology etc.

AVA analyzers have main advantages:

• No metallic mercury required to form the indication surface of the working solid carbon electrode; 
• no additional equipment required such as ultraviolet irradiation, gas supply (Argon, Nitrogen, Ozone and other), no need the additional attachments for element determination;
• the instrument functions in a laboratory with no exhaust system;
• AVA-Win software allows for simultaneous measuring up to four probes and maintenance of operational control over repeatability and accuracy of the measurements.
• working electrode sensitivity recovery is achieved by means of mechanical or electro-chemical polishing of the indication surface (once in two months);
• high reliability of the product as consequence of 30-year experience shared and implemented by the developers and producers of analogous equipment (the manufacturer has produced AVA-3, AVA-2, AVA-1, SVA, SULFAT and other analyzers)

Advantages of the AVA analyzer in comparison with instruments implementing other methods of analysis (AAS and other):

• High sensitivity for the most frequent toxic elements (eg. Cd, Pb sensitivity reaches 0,01 mgr/dm3);
• Ability to define ions of elements with different valency (eg. toxic valency forms of As(III), Cr (VI));
• High reproducibility of current-potential curves;
• Ability to define up to three elements in
