Twenty Years Specializing in Air Pollution Control by Catalysis, SCR NOx Reduction, and Platinum Group Metals Technologies and Markets. Our Materials Characterization and Catalyst Development Laboratory performs Novel Research, Benchmarking and Catalytic Activity Testing.

SCR Catalyst Testing

Taking Samples of SCR Catalyst

Sampling SCR Catalyst

As leaders in the SCR service industry, Environex owns and operates a full-service catalyst test laboratory.  As the only independent catalyst testers in the country, we offer unbiased results regarding your catalyst replacement needs. We have extensive data on all catalyst types in our database.

Catalyst Performance Testing

Testing the performance of your catalyst allows us to determine the rate of deactivation and to make predictions about future performance and durability. Our custom built catalyst testing equipment allows us to replicate a wide range of catalyst operating environments. We help identify problems before they become costly mistakes.

Physical and Chemical Analysis

The performance testing is supplemented with important physical and chemical analyses to diagnose the causes of catalyst performance loss. We offer the fastest testing turn-around time in the industry to help in those situations when timing is critical. The physical and chemical analysis give important clues to remedial actions that extend the life of the catalyst.

Catalyst tests commonly offered:

  • Electron Microscope (SEM)
  • BET Surface Area
  • Pore Size Distribution
  • ICP-MS (Contaminants)
  • EDS (Elements)
  • ESCA (Surface Contaminants)
  • XRD (Overheating)
  • XRF (Major Impurities)
  • TGA/DSC
