An exact match between the theoretical composition, calculated assuming a quantitative yield of polymerisation, and the analytical results indicates that the polymerisation has incorporated all monomers stoichiometrically in high yield. Likewise nitrogen is converted to nitrogen gas. For instance carbon and hydrogen are determined in organic compounds by conversion through combustion to carbon dioxide and water followed by quantitative analysis of the latter compounds.
A known amount of unknown substance is converted to simple, known compounds containing only the element to be quantified. Hall, in Techniques and Instrumentation in Analytical Chemistry, 2001 2.11.1 Elemental analysisĮlemental analysis is the classical method to obtain information about the elemental composition of an unknown substance.
