Abstract

The stable isotopic labeling reference materials play an indispensable role in the verification and calibration measuring instruments, evaluation analysis methods, determining the material characteristic and the quality control in the process of production. Therefore, it has great economic and social benefits in international trade, environmental protection, human health and safety. This paper studied the analysis of stability of Sudan-I-D5. The isotopic abundance of D and chemical purity have been analyzed. Samples which chemical purity and isotopic abundance are more than 99%, were packed in a dry and clean laboratory. analysis of stability of the isotope abundance and chemical purity of Sudan-I-D5 has been performed. Outliers do not appear within the tracker (for 12 months) at the temperature of 20℃ and avoid light conditions. The isotopic abundance and the chemical purity have been analyzed in the subsequent period of 12 days, after been saved ten hours in the (40±5) ℃ or (-20±5) ℃ transport conditions. The results show that the isotopic abundance and the chemical purity of Sudan-I-D5 are stable.
