The Dumas method is used for the quantitative determination of nitrogen in different substances based on a method of over a century and a half ago. Known also as “Combustion method”, it ensures precise results in few minutes, breaking down the sample into its elemental compounds. Substances produced, such as H2O, O2 and CO2, are trapped, in order to ensure the correct detection of the nitrogen.
It’s an alternative to Kjeldahl method for the determination of nitrogen and protein content in different types of sample.
Dumas method is the faster official one, validated by different International Organizations, such as AOAC, AACC, ASBC, ISO, IFFO, OIV, etc.
