CHNS Analysis

Introduction:

Coal is still the second-largest source of energy in the world and the most-used fuel for electricity generation. Eurofins spectro helps companies to attain maximum output in the amount of energy produced by assisting in maintaining the quality of fuel used. The process that we use to analyse the petroleum products is the CHNS Analyzer. CHNS elemental analysers provide a means for the rapid determination of carbon, hydrogen, nitrogen and sulphur in organic matrices and other types of materials. Eurofins Spectro helps to characterize the materials and provide information that can be utilized in calculating material/energy balances and efficiencies, as well as emissions potentials if the material is utilized as a fuel using the CHNS Analyzer technique.

CHNS Elemental Analysis:
