More Information :



EMGA-920 O/N analyzer: It's a "New flagship model” for O/N analyzers and user friendly product. This is an oxygen and nitrogen elemental analyzer with high accuracy and repeatability suiting to cutting-edge technology's R&D as well as quality control in the market of steel, new materials, catalyst and so on.   This is a new generation model optimized to fit to user's requests. The oxygen is measured as carbon monoxide and carbon dioxide by a non-dispersive infrared detector and the nitrogen by a thermal conductivity detector.


  • Super High Performance
  • User-friendly software
  • Fully Supported Accessories give simple operation
  • Improved Mechanism
  • Dual Sample/Flux introduction mechanism


EMGA-920:Oxygen/Nitrogen analyzer Principle
Oxygen:Non Dispersive Infrared detector
Nitrogen:Thermal Conductivity detector(TCD) Measurement range*:
Oxygen:0-5%, Nitrogen:0-3%
*Up to 100% wt is possible by decreasing the sample weight. Sample weight: 1,0 ± 0,1g Sensitivity(Minimum reading): Oxygen/Nitrogen: 0.0000001%(m/m) Accuracy**(Repeatability)
σn-1≦0.02%(m/m) or CV≦0.5% whichever is larger (Reference gas)
σn-1≦0.3%(m/m) or CV≦1.0%  whichever is larger (Standard sample)
** Based on the sample weight 1,0 ± 0,1g and with automation functions described below Display
