Oxygen / Nitrogen / Hydrogen Analyzer
The ELEMENTRAC ONH-p determines oxygen, nitrogen and hydrogen in inorganic samples by inert gas fusion in an impulse furnace with temperatures in excess of 3.000 °C.
The ELEMENTRAC ONH-p guarantees precise and fast sample analysis. The analyzer covers a wide range of applications such as metal, ceramics and other inorganic materials.
The ELEMENTRAC ONH-p can be supplied with up to two infrared cells with different path lengths, accommodating both high and
alloys, cast iron, ceramics, copper, refractory metals, steel, …

Operation of the ELEMENTRAC ONH-p is simple and safe. The samples are weighed on the interfaced balance and the weight is transferred to the linked PC. Manual weight entry is also possible.
Depending on the application the sample has to be placed in a nickel basket or capsule. Granulates or pins made of steel can be placed directly on the sample port without any other tools. Some applications require additional fluxes like tin or nickel, which have to be given in an empty graphite crucible. This graphite crucible is placed on the lower electrode tip and then the analysis is started. Typical analysis time is about 2.5 minutes.
All cell outputs and analyzer parameters are displayed in real time and are saved in a data base along with the results. Of
Measuring Principle ELEMENTRAC ONH-p
The measuring principle of the ELEMENTRAC ONH-p allows for a wide measuring range. To analyze the sample, it is weighed and placed on the sample port. Flushing with carrier gas prevents atmospheric gas (oxygen and nitrogen) from getting into the furnace.
The graphite crucible is outgassed in the impulse furnace to reduce possible contaminations (e.g. residual hydrogen). After a stabilization
The CO2 is measured by the infrared cells to determine the oxygen content. CO2 and water are removed chemically and the nitrogen content is measured in the thermal conductivity cell. In the case of hydrogen
