CHNS-O Analysers : Carlo Erba EA 1108 & Thermoquest-Fissons EA 1110

CHNS Analyzer(Elementar, Vario EL)

Principle

This analyzer works according to the principle of catalytic tube combustion in an oxygenated CO2 atmosphere and high temperatures.

Functional Diagram

Theory

The combustion gases are freed from foreign gases (for instance volatile halogen). The desiredmeasuring components are separated from each other with the help of specific adsorption columns and determined in succession with a thermal conductivity detector (TCD). Helium (He) serves as flushing and carrier gas.

Core Operations includes

  • Combustion
  • Gas separation
  • Gas detection

Applications

  • Rapid determination of carbon, hydrogen, nitrogen and sulphur inorganic matrices
  • Capable of handling solids, liquids, volatile and viscous samples, in the fields of pharmaceuticals, polymers, chemicals, environment, food and energy.
