EVISA is not only informing about all aspects of chemical speciation but is actively promoting research in this field.

Research supported by EVISA is meant to:
  • provide easy and robust methods for speciation analysis
  • enhance the quality of analytical results and the information provided by speciation analysis
  • enhance the knowledge about the biological activity, function and toxicity of chemical species
