ATS generally uses a LECO Combustion instrument to analyze carbon and sulfur content in small steel samples that do not meet the size constraints of Optical Emission Spectroscopy (OES analysis).

How Combustion Testing Works

Combustion testing is a technique used to precisely determine the content of carbon, sulfur, nitrogen, oxygen, and hydrogen in metals and alloys. Fundamentally, this process involves burning the sample to release these specific elements. The values received for element percentages are matched against specifications to determine the metal type. ATS frequently performs this analysis on steel samples in addition to iron, nickel, titanium, and cobalt alloys.

Commonly Tested Analytes

  • Steels and Cast Irons
  • Reactive Materials
  • Refractories
  • Non-Ferrous Alloys
  • Carbides
  • Carbon
  • Sulfur
  • Nitrogen
  • Oxygen
  • Hydrogen
