  • Elementrac ONHp-2 Brochure – Eltra

The new ELEMENTRAC ONH-p 2 is a powerful and robust elemental analyzer for measurement of oxygen, nitrogen and hydrogen 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 ONH-p 2 elemental analyzer meets or exceeds the requirements of all relevant international standards such as ASTM E 1019 or DIN EN 3976.

Key Features

Elementrac ONH-p

  • Low gas consumption and high sensitivity due to closed gas system
  • Easy application of pins, powders and granules
  • Inexpensive argon as carrier gas possible
  • Short analysis time
  • Powerful impulse furnace with 8.5 kW
  • Optional Autocleaner
  • Reliable OH elemental analysis of inorganic materials like steel, non-ferrous metals, ceramics, slags, ores, etc

Operation and Analysis Process

Step 1: Logging the sample into the ELEMENTS software

The sample ID is logged into the software and the weight is automatically transferred (see step 2).

Step 2: Weighing and introduction of sample into the port

The ELEMENTRAC OH-p 2 analyzes volumes from a few mg up to 2 grams safely and precisely. Rod-shaped or granular samples can be applied directly. For the elemental analysis of powders, a capsule is recommended which does not have to be sealed.

Step 3: Analysis

The empty graphite crucible is then placed on the lower electrode and the elemental analysis is started via the ELEMENTS software. The software controls all subsequent process steps.

Step 4: Data output and export

120 to 180 seconds after the analysis has started, the measured concentrations are available for export as a report or via LIMS.
