For the determination of Oxygen, Nitrogen and Hydrogen, the solid sample is fused in a graphite crucible under a flowing inert gas stream. The freely programmable temperature of the electrode furnace is monitored and controlled by a contact-free optical sensor. The evolved measuring gases CO, N2 and H2 are swept by the carrier gas to the high-stable, sensitive detection system, consisting of a selective NDIR-detector for CO (or optional two) and a thermal conductivity cell (TCD) for the detection of N2 or H2. The calibration can be made using reference material (standard samples) or by means of an optionally built in gas dosing unit. An integrated cleaning system for the impulse furnace and an automatic crucible loader, are available as options as well as an external hot extraction furnace with a quartz tube for the determination of diffusible hydrogen.

The Application

The G8 GALILEO is suitable for the rapid determination of Oxygen, Nitrogen and Hydrogen in many different kinds of material, e.g. steel, iron, alloys, non-ferrous metals, aluminum, titanium and alloys, zirconium and alloys, ores, ceramics, cement and many more.

The Software

The analysis software of the G8 GALILEO is clear and simply structured. All tasks to be performed by the software are clearly divided into four different screens.
