Stripping voltammetric determination of heavy metal ions using the UNICHROM hardware and software complex

Posted on by

Scope: chemical analysis of natural and waste water, process solutions in the chemical, petrochemical, food industries

Main advantages:

  •  expressiveness
  • possibility of automatic and manual identification of each component
  • maintaining a library of definitions
  • export to third-party applications for organizing and analyzing the results of determinations within the enterprise
  • the ability to work with any measurement technique
  • convenient user interface
  • scalability to the needs of a particular laboratory

The hardware and software complex can be adapted to the needs of the customer to work with various analytical equipment: polarograph PU-1, voltammetric analyzers AVA and TA

Metrological characteristics:

  • relative error: 20% at ion concentration 50-
  • 500 μg / L, 25% – at 1-50 μg / L and 50% – at 0.3-1 μg / L
  • detection limit: 0.1 μg / L for Cd2 +, Pb2 + and 5 μg / L for Zn2 +
  • working range of concentrations: for Cd2 +, Pb2 + 0.3-200 μg / l
  • for Zn2 + – 10-500 μg / l
  • selectivity: ions of alkali and alkaline earth metals do not interfere, most inorganic ions

Comparison with analogs: carrying out chemical and analytical determinations using the developed software and hardware complex allows to reduce the cost and speed up the analysis

Significance: the implementation of constant analytical monitoring of the content of heavy metal ions in natural and technological objects is of significant importance in monitoring the state of the ecological situation
