Chemical analysis for industrial processes optimization

Today, companies need to respond to an increasing number of constraints:

  • Environmental constraints, to comply with a more and more severe legislation (emissions, use of hazardous materials, limitation of water consumption, etc…)
  • Quality constraints, with the new certifications implementation
  • Economical constraints, with a compulsory reduction of production costs

The answer to these constraints requires a research and development effort and a rigorous monitoring of the processes.

By the knowledge of the chemistry in solution and the understanding of the chemical mechanisms of attack we can help you to optimize the efficiency of the treatments, extend the serviceable life of chemical solutions, be in accordance with the REACH regulation or better manage the impact of emissions on the environment.
