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.

Advantages

• 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

Application

Alloys, Cast Iron, Ceramics, Copper, Refractory Metals, Steel, etc.
