Application of Combustion Method to the Determination of Total Nitrogen in Beer, Low-Malt Beer, and Third-Category Beer

摘要

1. Relative repeatability standard deviation (RSD_r) and repeatabil-ity limit (r_(95)) for determination of total nitrogen by the com-bustion method ranged from 0.8 to 4.1% and from 12.6 to 34.5 mg/L, respectively, and were judged acceptable. 2. Relative reproducibility standard deviation (RSD_R) and repro-ducibility limit (R_(95)) for determination of total nitrogen by the combustion method ranged from 3.0 to 11.9% and from 36.6 to 115.4 mg/L, respectively, and were judged acceptable.
