INSTUMENTS FOR RESEARCH LABORATORIES

The automatic complex to measure the half-waves of oxidation and reduction of organic, inorganic and coordination compounds
The automatic complex is performed on the basis of the voltammetric analyzer "Ecotest-VA" with the rotating disc electrode.
"Ecotest-VA": the main unit
    The field of applications:
  • the possibility to measure in the standard conditions the half-waves of oxidation and reduction of organic, inorganic and coordination compounds
  • determination of the potentials of the peaks of oxidation and of reduction by means of the method of the cyclic voltammograms
  • the measurement of the diffusion coefficiencies of the electroactive species
  • wide range of chemical analysis
    The shipping kit:
  • the main unit of "Ecotest-VA" with accessories
  • the electrode system for the aqueous and non-aqueous solutions, including acetonitrile
  • the rotating disk-stand with accessories
  • instruction manual
  • software
Examples of the experimental results

The voltammograms of ferrocene (Fc), formylferrocene (Fc-CHO), ferrocene-carbonic acid (Fc-COOH) measured on the rotating platinum disc electrode in acetonitrile

The cyclic voltammogram of ferrocene measured on a still platinum disc electrode in acetonitrile

The voltammograms of ferrocene (Fc), measured with the different rate of rotating of the platinum disc electrode in acetonitrile

The plot of the limit diffusion current versus the square root of the rotation rate of the platinum disc electrode for 10-3 M solution of ferrocene in acetonitrile

    The use of the robotized complex "Expertise-VA-2D
  • The automatic periodical monitoring of slow processes by means of voltammetry
  • Multiple repeat of the like measurements with different samples
