Description

LECO’s ON736 Oxygen/Nitrogen Elemental Analyzer is designed for routine measurement of oxygen and nitrogen content of inorganic materials, steel, ferrous and nonferrous alloys, and refractory materials using the inert gas fusion technique.

The ON736 instrument is compliant to ASTM and ISO approved methods.  It is perfectly suitable for elemental analysis of reactive/refractory metals, like Titanium, Tantalum, Zirconiumand their alloys.

The instrument features a custom MS Windows®-based software interface designed specifically for touch-screen operation. Developed by combining long-term research with customer feedback, this easy-to-use software gives you complete access to instrument control, analysis settings, diagnostics, reporting, and more—without sacrificing valuable bench space.

Benefits :

  • Analysis time 100 seconds
  • Accuracy and precision to low-ppm levels
  • High-Performance LECO detectors assure results quality, drift-free and long-life operation
  • Modern Cornerstone software : easy of use with reach functionalities
  • Well engineered ergonomics and convenience of use with bench space saving
  • Optional auto cleaner minimize need for cleaning between analysis
  • Reliable Automation available for increased workload

 

A number of models and configurations are available for 736 Series to fit your particular needs.  Please contact us for more details.

Operation

The ON736 is designed for fast simultaneous determination of oxygen and nitrogen content in steel and other inorganic materials.

Samples dropped into the hot crucible fuse (melt) and release forms of oxygen, nitrogen and hydrogen Oxygen species react with hot graphite to form carbon monoxide (CO) and carbon dioxide (CO2) Nitrogen species form elemental nitrogen (N2)
Gases are swept out of the crucible by an inert carrier gas flow (helium or argon)
The gases flow through a heated reagent oxidizing CO to CO2.
Oxygen is detected as CO using a non-dispersive infrared (NDIR) cell.
After scrubbing out H2O and CO2 from the flow, the DFC compensates for the loss with carrier gas and Nitrogen is measured as N2 by TC detector

 Features and Benefits :

  • Integral Sample Loading Area minimizes atmospheric contamination during sample introduction
  • Jam Free Sample Drop
  • Choice of either argon or helium carrier gas
  • Novel electrode design increases heat transfer efficiency for increased stability
  • High efficiency cooling
  • Built in vacuum cleaner keeps working area clean
  • Thermostated detector design with built-in drift compensation circuitry
