 note = {The δ ^<13>C of the New Oxalic Acid Standard (NBS-RM-49) taken from the same bottle was measured by a mass spectrometer (Finnigan MAT-252). The δ ^<13>C of 11 samples ranged from -17.603 to -17,553‰, and averaged -17.5816±0.0045‰. The average value coincided with the internationally authorized value of -17.6±0.1‰. The overall uncertainty was less than 0.026% by one standard deviation. The NBS-RM-49 sample was considerably homogeneous., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1997 (平成9)年度},
