The Dumas Method, The Increasingly Used Technique
The Dumas method, also known as combustion method, is considered as an alternative to the classical Kjeldahl method. In fact, both of the methods are validated by different international organizations: Kjeldahl is officially recognized by AOAC, EPA, DIN, ISO, etc., whilst Dumas by AOAC, AACC, ISO, DIN, ASBC, AOCS, OIV, etc. However, in some countries the local guidelines recommend one method rather than the other. This is the reason why many decision makers and users are undecided between the two methods and between following the local guidelines or the International Standards.
Dumas nitrogen / total nitrogen content
The original method was developed by Jean-Baptiste Dumas during his studies in 1831, even before the Kjeldahl analysis.
Nitrogen analyzer / elemental analysis
VELP Scientifica has developed a powerful Dumas Protein/Nitrogen Analyzer, able to perform precise nitrogen analysis and protein determination in a flash.
