Inert Gas Fusion (IGF) analysis, commonly performed using LECO instrumentation, is a precise analytical technique used to determine the concentration of oxygen, nitrogen, and hydrogen in metallic materials. These elements, even at trace levels, can significantly affect mechanical properties, performance, and reliability.
During analysis, a sample is melted in a high-temperature furnace under an inert gas atmosphere, releasing gases that are quantitatively measured. IGF analysis is widely used for quality control, material certification, and compliance with industry standards.

Valtech-MT provides accurate and repeatable inert gas fusion analysis to support material verification, production control, and failure investigations.
