摘要：

The carbon, hydrogen, and nitrogen (CHIN) contents of alanine and their uncertainties were estimated using a CHN analyzer and the certified reference material (CRM) L-alanine. The CHIN contents and their uncertainties, as measured using the single-point calibration method, were 40.36 +/- 0.20% for C, 7.86 +/- 0.13% for H, and 15.66 +/- 0.09% for N; the results obtained using the bracket calibration method were also comparable. The method described in this study is reasonable, convenient, and meets the general requirement of having uncertainties <= 0.4%.
