CHN Analysis is a form of Elemental Analysis concerned with determination of only Carbon (C), Hydrogen (H) and Nitrogen (N) in a sample. The most popular technology behind the CHN analysis is combustion analysis where the sample is first fully combusted and then the products of its combustion are analyzed.
The full combustion is usually achieved by providing abundant oxygen supply during the combustion process. In this setup the analyzed products: Carbon, Hydrogen and Nitrogen oxidize and form carbon dioxide - CO2, water - H2O, and nitric oxide - NO, respectively. These product compounds are carefully collected and weighted. The weights are used to determine the elemental composition, or empirical formula, of the analyzed sample.
