Oxygen | Nitrogen  Analyzer

The new ELEMENTRAC ON-​​​​​​​p 2 is a powerful and robust elemental analyzer for measurement of oxygen and nitrogen concentrations in inorganic materials like steel, iron, copper or ceramics. The highly sensitive NDIR and thermal conductivity detectors reliably detect element concentrations from low ppm content to high percentages.

The innovative sample port system with pulsed chamber rinsing and vertical sample drop allow for user-friendly and comfortable analysis of rod-shaped, granular or powdery samples with a weight of up to 2 grams.

The ELEMENTRAC ON-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 or 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. The ELEMENTRAC ON-p 2 elemental analyzer uses an ON mode with helium carrier gas (optionally argon)  to determine the oxygen and nitrogen content.

The chemicals and filters required for the operation of the ELEMENTRAC ON-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.

The ELEMENTRAC ON-p 2 elemental analyzer meets or exceeds the requirements of all relevant international standards such as ASTM E 1019 or DIN EN 3976.

Typical sample materials: alloys, aluminum, ashes, carbides, cast iron, copper, ferroalloys, iron, metals, ores, refractory metals, silicon, steel, etc.
