摘要：

A combustion method, relying on the Dumas principle, for the determination of total nitrogen in barley and malt, has been collaboratively tested by the Analysis Committee of the European Brewery Convention. Repeatability, r(95), and reproducibility. R(95), values were 0.063 and 0.116% of dry matter. respectively. for samples with nitrogen contents in the range 1.23 to 1.86% hi of dry matter. There was no significant difference between these values for barley and malt. The Analysis Committee approved the adoption of the combustion method for inclusion in Analytica EBC as an alternative method.
