ONH-330 Oxygen/ Nitrogen/ Hydrogen analyzer equipped with 8.0KW electrode impulse furnace , with temperature in excess of 3000℃, The electrode pulse furnace can increase the temperature by program. The power control or current control can be selected to achieve the best melting of the sample.
The use of inert gas (argon, helium, nitrogen) as carrier gas is determined by analysis elements, samples of various metallic & non-metallic materials such as ferrous metals, non-ferrous metals, ceramic materials, superconducting materials, and semiconductor materials are thermally decomposed at a high temperature. Oxygen in the sample reacts with carbon in the graphite crucible to produce CO, and nitrogen and hydrogen respectively escape as N2 andH2.
The carrier gas sends mixed gases to the reformer. CO is converted to CO2, and the mixed gas passing through the reformer is sent to the infrared detection system for detection, the mixed gas containing N2 and H2 is sent to a thermal conductivity detector after the CO2 and other components are removed. Infrared detection systems and thermal conductivity detection systems process the measured signals through amplification, A/D conversion, etc. and send them to a computer for data processing to calculate the content of oxygen and nitrogen in the sample.
