Analytical Chemistry Testing - Clark Testing

Analytical Chemistry Testing



Clark specializes in routine analysis and comprehensive investigative chemical testing for a wide range of industries. The Analytical Chemistry Lab ensures high quality performance through analytical expertise, documented test procedures, and stringent quality guidelines.

Clark is accredited under ISO/IEC Guide 17025. Testing is performed in accordance with ASTM, API, and other approved applicable methods. Additionally, we have experience utilizing chemical techniques to develop new methods.

A few examples of routine analysis include that of ferrous and nonferrous metals, process solutions, and petroleum products. In addition, our capabilities include analysis of raw materials and by-products such as steel additives, fluxes, ceramics, refractory, slag, lime, pellets, scrap, bag house dust, coal and coke, as well as other industrial materials for the chemical composition.

Many of our customers have common goals. They are in need of testing services for Product Comparison, Product Verification, or Failure Analysis.

Routine Testing includes, but not limited to:


  • Alloy Analysis
  • Coating Analysis – Coating Weight and Composition
  • Metal Fines and Soaps on Sheet
  • Elemental analysis
  • Elemental Oxides
  • Surface Cleanliness on Sheet
  • Anions – Chloride, Sulfate, Phosphate, Nitrate
  • Carbon, Sulfur, Oxygen, Nitrogen
