LECO Combustion Analysis

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).

• Carbon & sulfur analysisAfter 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 the flowing stream of inert argon gas, SGS MSi chemists measure fusion gases by thermal conductivity. During the process hydrogen is released as H2.

LECO Carbon Analysis

In many industrial and manufacturing applications, a precise elemental composition is necessary for optimized performance and product longevity. Depending upon your project requirements, SGS MSi Testing & Engineering uses chemical and mechanical test methods to determine the composition of your metal or alloy sample.

Utilizing state-of-the-art LECO instrumentation, SGS MSi’s experienced engineering team offers carbon analysis for metal and alloy samples. The LECO system requires only a nominal sample weight, and analysis involves oxidizing the sample material using an induction furnace. During the combustion process, carbon is converted to CO2 and measured with an infrared detector. Through this innovative technique, SGS MSi engineers can accurately determine the carbon content of any provided metal or alloy.

LECO Nitrogen Analysis

In many industrial and manufacturing settings, a precise metal or alloy composition is required for optimized performance and product longevity. Depending upon your project-specific needs, the SGS MSi Testing & Engineering team uses mechanical and chemical testing methods to determine the composition of your metal or alloy sample.

To ensure accuracy, SGS MSi relies on state-of-the-art LECO technology to provide nitrogen analysis for steel, iron, nickel and cobalt alloys. Delivering elemental results quickly and precisely, LECO’s Nitrogen Determinator is designed for nominal sample weights. Using inert gas fusion techniques, LECO’s field-proven instrumentation allows our industry-leading metallurgical engineers to accurately determine the nitrogen content of any metal or alloy.
