The Bruker G8 GALILEO ONH-TDA is a high-precision elemental analyzer designed for the rapid and accurate determination of oxygen (O), nitrogen (N), and hydrogen (H) in solid inorganic materials, utilizing the inert gas fusion (IGF) technique. This method involves melting the sample in a graphite crucible under a controlled inert gas atmosphere, typically helium, at temperatures up to 2500?°C. The evolved gases are then quantified using infrared and thermal conductivity detector (TCD) detector providing direct measurements.
For AM applications, the G8 GALILEO is particularly suited for analyzing metal powders, such as titanium, aluminum, nickel and steel alloys, where precise measurement and control of light element concentrations is critical. The instrument's capability to measure both total and diffusible hydrogen content is essential for assessing hydrogen-induced defects in AM parts. The system is equipped with an infrared furnace that allows for the determination of diffusible hydrogen through thermal desorption analysis (TDA).
