The accuracy (% relative error) and precision were satisfactory, with mean values of 5 +/- 4 and 3 +/- 2, respectively. This procedure has been used to estimate nitrogen content in samples before and after Kjeldahl treatment. In the same samples, the N found for the untreated samples ...
Determination of crude protein was done using the micro Kjeldahl nitrogen method which involves the digestion of a given weight of the sample with concentrated H2SO4 and a catalyst to convert any organic nitrogen to ammonium sulfate, (NH4) 2SO4 in solution followed by the decomposition of ...
Estimations of total nitrogen by the Kjeldahl method have been made for a number of years, but this method is too intricate for general clinical use and can be carried out only by trained chemists in well-equipped laboratories. From the determinations made by this method, however, it was ...

NITROGEN CONCENTRATIONREGRESSIONYIELDThe nutritional diagnosis of crops is carried out through costly elemental analyses of different plant organs, particularly leaves, in the laboratory. However, visible and near-infrared (Vis-NIR) spectroscopy of unprocessed plant samples has a high potential as a ...
The N1s photoelectron peaks of some varieties of barley and maize meals showed a pronounced shoulder on the high binding energy side. On deconvolution into two components the main peak was assigned to nitrogen in the peptide bond and the smaller peak was assigned to the protonated nitrogen on ...
