Eltra Analyzer ELEMENTRAC ONH-p

Eltra  Analyzer ELEMENTRAC ONH-p | Oxygen / Nitrogen / Hydrogen

The ELEMENTRAC ONH-p determines oxygen, nitrogen, and hydrogen in inorganic samples by inert gas fusion in an impulse furnace with temperatures in excess of 3.000 °C. The ELEMENTRAC ONH-p guarantees precise and fast sample analysis. The analyzer covers a wide range of applications such as metal, ceramics, and other inorganic materials.

The ELEMENTRAC ONH-p can be supplied with up to two infrared cells with different path lengths, accommodating both high and low-level oxygen analyses. Nitrogen and hydrogen concentrations are determined in the ELEMENTRAC ONHp by a robust and sensitive thermal conductivity cell.


  • Simultaneous oxygen/nitrogen or oxygen/hydrogen determination with inert gas fusion technique
  • NEW: closed gas management and optimized gas circulation for sensitive ONH determination
  • NEW: use of cost-efficient argon as carrier gas possible
  • NEW: powerful catalyst furnace for precise oxygen measurement
  • NEW: gas flow system with electronic gas flow control and new leakage test
  • NEW: water-cooled sample port system for effective removal of atmospheric gases
  • Flexible configurations and measuring ranges for O, N, and H
  • High sensitivity IR and TC cells with low detection limits
  • Short analysis time
  • Powerful 8,5 kW* impulse furnace for temperatures in excess of 3,000 °C
  • Economic analysis of grains without capsules
  • NEW: chemicals and tubes are hidden behind a door (removable)
  • NEW: powerful software (supporting data and application export, comment fields, and many more)
  • Single and multi-point calibration (linear regression)
  • NEW: cooling via tap water or heat exchanger or chiller
  • New design allows operation in production control and laboratory
