CHNS analysis of organic materials

Determination of carbon, hydrogen, nitrogen, and sulfur content of the organic sample. CHNS analysis is performed using Dumas combustion method, where the sample is combusted at elevated temperature followed by gas chromatography separation and detection using thermal conductivity. The sample can be either solid or liquid, but water in the sample affects the result. In the case of aqueous samples, it is possible to dry the sample before analysis. The price includes two parallel measurements. The results are reported as wt-% of the initial sample. The analysis gives the total carbon, hydrogen, nitrogen, and sulfur content of the material, but it does not identify any chemical structures.
