  • Determines weight percent of carbon, hydrogen, nitrogen, sulfur or oxygen
  • Built with EA Data Manager software
  • Adopts frontal chromatography for simple, reliable and accurate measurements
  • Multiple modes of operation: CHN or CHNS Mode or Oxygen Mode.
  • Readily/conveniently switches between Oxygen and CHN/CHNS modes
  • Analysis Times: CHN – 6 mins; CHNS – 8 mins; Oxygen- 4 mins
  • Analytical range: C 0.001-3.6 mg; H 0.001-1.0 mg; N 0.001-6.0 mg ; S 0.001-2.0 mg ; O 0.001-2.0 mg
  • Sample required for analysis: 1-3 mg
  • Detector TCD (thermal conductivity detector).
  • Carrier Gas: Helium.
  • Combustion gas: Oxygen.
  • Adopts a mixture of two combustion techniques to ensure complete sample combustion.
  • Pneumatic Gas; Air, Nitrogen or Argon.
  • The weight of the samples is manually fed to the system (automatic sample weight feeding is also possible – least preferred)
  • Laboratory environment: Temperature range 12 to 25 ºC; Humidity 20 – 80% non-condensing
  • Accuracy: ≤ 0.3% – In Helium carrier gas and certified reference materials
  • Precision: ≤ 0.2% – In Helium carrier gas using certified reference materials
  • Detects and quantifies Carbon, Nitrogen, Hydrogen, Oxygen and Sulfur
