ISO 19051:2015 specifies a test method for the determination of nitrogen content of raw natural rubber using the Micro Dumas combustion method. This method is also applicable to natural rubber latex.
Abstract
Overview
ISO 19051:2015 specifies a laboratory test method for determining in and using the . The Micro Dumas approach is a rapid elemental combustion technique that converts sample nitrogen to gaseous forms, reduces oxides to N2, and quantifies nitrogen using gas detection (e.g., GC-TCD or infrared/TCD cells). Compared with Kjeldahl, the method is and is suitable for routine quality control and research.
