Description
OXYGEN / NITROGEN / HYDROGEN ANALYZER ELEMENTRAC ONH-P 2
CONFIGURATIONS
The ELEMENTRAC ONH-p 2 elemental analyzer is available as a single-element analyzer for oxygen, nitrogen or hydrogen only, or in a multi-element configuration for measuring ON, OH, NH, or ONH. Whereas oxygen is determined as CO2 in up to two infrared cells, nitrogen and hydrogen are detected in their elemental form in a thermal conductivity cell. The ELEMENTRAC ONH-p 2 elemental analyzer uses an ON mode with helium carrier gas (optionally argon) and an OH mode with nitrogen carrier gas to take advantage of the sensitive thermal conductivity cell.
INTEGRATED STANDARD SOLUTIONS
The chemicals and filters required for the operation of the ELEMENTRAC ONH-p 2 elemental analyzer are arranged conveniently on the front panel and can be concealed behind a removable door during routine operation. This arrangement significantly reduces the time required for maintenance and increases user-friendliness. In addition, innovative details considerably improve the reproducibility of measurements.
Options
In addition to the integrated solutions of the ELEMENTRAC ONH-p 2, further options are available to increase efficiency and extend the application range of your elemental analysis.

FUNCTIONAL PRINCIPLE
The measuring principle of the ELEMENTRAC ONH-p 2 elemental analyzer 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 of the analyzer to reduce possible contaminations (e.g. residual hydrogen). After a stabilization phase the sample is dropped into the crucible and melts. Carbon monoxide is produced by the reaction of carbon in the graphite crucible and oxygen of the sample. Nitrogen and hydrogen are released in its elemental form. The carrier gas (helium) and sample gasses pass through a filter before entering a copper oxide catalyst which converts the CO to CO2.
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 analysis, nitrogen carrier as well as sample gas pass through a Schuetze reagent instead of a copper oxide catalyst. As an option the less expensive Argon can be used to determinate the oxygen and nitrogen content during analysis.
