O-N-H Analysis of Solid Samples in a Wide Concentration Range

Aug 02 2023

Eltra’s new ELEMENTRAC ONH-p2 is a powerful and robust elemental analyser for measuring oxygen, nitrogen and hydrogen concentrations in inorganic samples. The high-detection NDIR and thermal detectors reliably measure elemental concentrations from low ppm levels to the high percentage range. Thanks to the innovative sample lock with pulsed chamber flushing and vertical sample drop, user-friendly and convenient analysis of rod-shaped, granular or powdered samples with a sample weight of up to 2 grams is easily possible.

The analyser can be configured for single-element or multi-element analysis. Oxygen is determined as CO2 in up to two infrared cells, nitrogen and hydrogen in elemental form in a thermal conductivity cell. The ELEMENTRAC ONH-p 2 uses an ON mode with carrier gas helium (optionally argon) and an OH mode with carrier gas nitrogen to take advantage of the sensitive thermal conductivity cell for nitrogen and hydrogen measurement.

The chemicals and filters required for operation are arranged in a user-friendly way on the front of the unit and can be concealed behind a removable door during routine operation. This arrangement significantly reduces the time required for maintenance and increases user-friendliness.

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