Elemental Analyzer for Analysis of CHNS

Full-text:Elemental Analyzer is typically used to measure the percentage of Carbon (C), Hydrogen (H), Nitrogen (N) and Sulphur (S) in a sample. It is a straightforward and a reliable analysis to assess purity and chemical composition of a compound. This allow for the determination of the structure of the compound which is beneficial for research and quality control purposes. This technique is based on "Dumas Method" which involves complete combustion and oxidation of the sample which produces CO₂, H₂O, NO₂ and SO₂. These gases get separated using gas chromatography and detected using thermal conductivity detector. CHNS analysis can be used on wide range of samples across many different industries such as environmental, food and animal feed, energy or petrochemical, material characterization, agricultural as well as pharmaceuticals.
