Combustion and inert-gas fusion analysis deliver precise bulk chemistry for critical elements, carbon, sulfur, oxygen, nitrogen, and hydrogen—in carbon/low alloys, steals, stainless steals, nickel, titanium and copper alloys. AADFW combines accredited methods, expert metallurgists, and faster turnaround than slow, global labs. Request a Quote or Explore Our Combustion Analysis Services. 

Carbon and sulfur testing

Why Combustion Analysis Matters

In flight-critical and high-pressure environments, some elements drive strength, toughness, corrosion/cracking susceptibility, weld quality, and heat-treat response. Accurate C/S/O/N/H values prevent alloy mix-ups, confirm melt and weld procedures, and keep lots moving through qualification, PMI, and final release. Combustion/fusion testing supports conformance to customer drawings and applicable industry standards with audit-ready documentation. 

Our Combustion Analysis Testing Services

  • Carbon & Sulfur by Combustion – High-precision combustion with IR detection quantifies C and S in ferrous and nonferrous alloys, essential for verifying melt chemistry, weld qualifications, and heat-treat targets. 
  • Oxygen, Nitrogen & Hydrogen by Inert Gas Fusion – Fusion and thermal conductivity/detection methods measure O/N/H at parts per millions(ppm) to percent levels to control embrittlement risks, porosity, and fatigue performance in high-integrity components. 
  • Weld & Overlay Interstitial Control – Targeted sampling of weld metal/HAZ overlays to confirm filler dilution and meet procedure limits for C/S/O/N/H. 
  • Failure & Contamination Screening – Elevated S, O, or H often flags process issues; we pair results with metallography or EDS when root cause is required. 
  • Sampling & Preparation – Matrix-appropriate machining/drilling, avoidance of lubricant contamination, and strict traceability from coupon to report. 
  • Methodology & QA – Matrix-matched calibration, certified reference materials, daily drift checks, duplicates, and control charts per accredited procedures and applicable ASTM/ISO methods. 

Industries We Support

  • Aerospace: Melt and heat-lot verification, weld procedure support, and composition control for high-performance alloys under OEM/FAA expectations. 
  • Oil & Gas: Pipe/tubulars, pressure components, weld overlays/cladding for sour/CO₂ service where S, H, and O drive cracking/corrosion risk. 
  • Defense & General Manufacturing: Mission-critical parts where toughness, fatigue life, and cleanliness demand tight element composition limits.
