Nitrogen


The Nitrogen content of a sample is the contribution that Nitrogen makes to the total mass of the sample. Click here for more information on the elemental composition of biomass.

We determine the nitrogen content according to the procedures outlined in European Standard EN 15104:2011 ("Solid biofuels - Determination of total content of carbon, hydrogen and nitrogen - Instrumental methods") and we use an Elementar Vario MACRO Cube elemental analyser which has been designed to satisfy the requirements of this method.

We report the nitrogen content on a dry-mass basis as well as on an as-received basis and a dry ash-free basis (providing that the ash content and as-received moisture content of the sample have also been determined). We use the calculations outlined in European Standard EN 15296:2011 ("Solid biofuels - Conversion of analytical results from one basis to another") to carry out these conversions.
