Voltammetric analyzer Ecotest-AVL-V
Voltammetric analyzer Ecotest-AVL-V is intended for the quantitative determination of electrochemically active and inactive elements and substances in water samples, aqueous solutions or extracts obtained from various materials, as well as for scientific research in the field of inorganic and organic chemistry, electrochemistry, metal corrosion, biotechnology, etc. The analyzer is also used to study the processes of deposition and dissolution of metals, electrode processes in chemical current sources, and determine the corrosion resistance of various materials. It is possible to jointly determine a number of elements in one sample. The limit of determination reaches 0.01 μg/l, which can be hundredths of the MPC with a maximum measurement error of 25%. The time of one analysis (including joint determination) is no more than 30 minutes. In terms of sensitivity and selectivity, the analyzer for determining microimpurities of elements is not inferior to expensive spectral instruments, such as atomic absorption spectrophotometers, etc. Ecotest-AVL-V provides operation in the mode of alternating current square-wave direct and stripping voltammetry with accumulation along one measuring channel.
