Description
OXYGEN / NITROGEN ANALYZER ELEMENTRAC ON-P 2
CONFIGURATIONS
The ELEMENTRAC ON-p 2 elemental analyzer is available as a single-element analyzer for oxygen or nitrogen only, or in a multi-element configuration for measuring ON. Whereas oxygen is determined as CO2 in up to two infrared cells, nitrogen is detected in its elemental form in a thermal conductivity cell.
INTEGRATED STANDARD SOLUTIONS
The chemicals and filters required for operation of the 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 ON-p 2, further options are available to increase efficiency and extend the application range of your elemental analysis.
Software
TYPICAL SAMPLE MATERIALS
Alloys, aluminum, ashes, carbides, cast iron, ceramics, copper, ferroalloys, iron, metals, ores, refractory metals, silicon, steel
FUNCTIONAL PRINCIPLE
The measuring principle of the ELEMENTRAC ON-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 material. 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 then measured by infrared cells to determine the oxygen content. CO2 and water are removed chemically and the nitrogen content is measured in the thermal conductivity cell. As an option the less expensive Argon can be used in the elemental analyzer to determinate the oxygen and nitrogen content.
