Description
OXYGEN / HYDROGEN ANALYZER ELEMENTRAC OH-P 2
CONFIGURATIONS
The ELEMENTRAC OH-p 2 is available as a single-element analyzer for oxygen or hydrogen only, or in a multi-element configuration for measuring OH. 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.
INTEGRATED STANDARD SOLUTIONS
The chemicals and filters required for the operation of the ELEMENTRAC OH-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 OH-p 2 elemental analyzer, further options are available to increase efficiency and extend the application range.
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 OH-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) 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. Hydrogen is released in its elemental form. The carrier gas (nitrogen) and sample gasses pass through a filter before entering the Schuetze reagent which converts the CO to CO2, whereas hydrogen remains in its elemental form.
The CO2 is measured by the infrared cells and removed chemically. Afterwards the hydrogen content is determined in the thermal conductivity cell.
