SGS MSi Testing & Engineering uses state-of-the-art LECO Determinators to provide superior accuracy when detection limits are low or samples are small. Analyzing a variety of metals and alloy combinations, LECO Combustion Analysis successfully detects low levels of carbon, sulfur, nitrogen, oxygen and hydrogen (from .0002 to .05 percent, depending upon the sample type).
Performed in accordance with ASTM E1019 and ASTM E1409, LECO Combustion Analysis methods include:
-
Carbon & sulfur analysis
After weighing your material, we heat and combust in the presence of pure oxygen. During the process, carbon and sulfur are oxidized to form CO2 and SO2.
-
Oxygen & nitrogen analysis
Incorporating gas fusion under a flowing stream of helium, SGS MSi engineers measure combustion gases through infrared absorption and thermal conductivity. During this process, oxygen and carbon combine to form CO2, and nitrogen is released as N2.
-
Hydrogen analysis
Incorporating gas fusion under a flowing stream of inert argon gas, SGS MSi engineers measure combustion gases by infrared absorption and thermal conductivity. During the process, oxygen combines with carbon to form CO2 and hydrogen is released as H2.
The SGS MSi team uses LECO’s industry-leading instrumentation to test carbon steel, stainless steel, alloy steels, cast iron, nickel alloys, titanium alloys and cobalt alloys. Partnering with the manufacturing, aerospace, marine, energy & power, heavy equipment, medical, foundry and other industries, our degreed engineers provide detailed reports of combustion analysis results and recommendations.
