Medical Laboratory Testing: Carbon/Sulfur Testing
Carbon/sulfur analysis measures these critical interstitial elements in metals and alloys using combustion or inert gas fusion techniques. Accurate results help verify material purity and maintain the right balance of strength, ductility, and corrosion resistance. For medical manufacturers, tight control of carbon and sulfur matters in stainless steel instruments, cobalt-chrome implants, titanium components, and other metallic devices.
Even small changes in carbon or sulfur can affect hardness, fatigue life, weldability, and corrosion resistance in the body or during repeated sterilization. Applus+ Reliable Analysis already maintains accredited combustion analysis capabilities for carbon and sulfur, along with its broader metallic testing, microhardness, and materials characterization methods.
These measurements support material qualification under ISO 10993-18 and key alloy specifications for implants and instruments. Manufacturers use the data to confirm supplier quality, validate heat treatment, and strengthen regulatory documentation for FDA and EU MDR submissions. Reliable Analysis delivers precise, reliable elemental results using equipment that already operates daily under its ISO/IEC 17025 accreditation.
Common Carbon/Sulfur Analysis Medical Testing Standards
ASTM E1019 for Determination of Carbon, Sulfur, Nitrogen, and Oxygen
ASTM E1019 covers the determination of carbon and sulfur, along with nitrogen and oxygen, in steel, iron, nickel, and cobalt alloys. It uses combustion or inert gas fusion followed by infrared or thermal conductivity detection. The method accurately measures these interstitial elements at low concentration levels.
Medical manufacturers use it to verify material purity and composition in stainless steel surgical instruments, cobalt-chrome orthopedic implants, and other metallic components. Controlled carbon and sulfur content helps maintain mechanical properties, corrosion resistance, and biocompatibility.
ISO 15350 Steel and Iron Infrared Absorption Method After Combustion
ISO 15350 specifies how to measure total carbon and sulfur in steel and iron by combustion in an induction furnace, followed by infrared absorption of the evolved gases. It delivers reliable, high-precision results for quality control. Medical-grade stainless steels and alloys for surgical instruments and implants use it to help demonstrate elemental purity for European MDR submissions.
ASTM F562 Standard for Alloys in Surgical Implant Applications
ASTM F562 defines the chemical, mechanical, and metallurgical requirements for a high-performance cobalt-nickel-chromium-molybdenum alloy used in surgical implants, including strict limits on carbon and sulfur content. The specification ensures the material achieves the necessary strength, ductility, and corrosion resistance. It is the primary standard for cardiovascular stents, orthopedic components, and other load-bearing implantable devices where low carbon and sulfur levels are critical for fatigue resistance and long-term clinical performance.
ASTM E1409 Determination of Oxygen and Nitrogen in Titanium and Titanium Alloys
ASTM E1409 measures oxygen and nitrogen in titanium and titanium alloys using inert gas fusion. It also extends to carbon and sulfur measurement with similar combustion techniques. The method provides accurate interstitial element data for high-purity titanium alloys.
Medical-grade titanium implants, bone screws, and joint replacements rely on tight control of carbon, sulfur, oxygen, and nitrogen. That control helps maintain biocompatibility, corrosion resistance, and mechanical properties.
