高效液相色谱法测定2,4-二氨基苯磺酸钠的纯度

Determination of Sodium 2,4-Diaminobenzenesulfonate by HPLC

本文采用高效液相色谱测定2,4-二氨基苯磺酸钠的纯度。对试样溶剂、分析条件进行了选择。在优化条件下,标准偏差SD为0.03,变异系数RSD为0.03%。

HPLC was employed to determine purity of sodium 2,4-diaminobenzenesulfonate. Solvent and analysis conditions were se- lected based on experiments. In optimum condition, the standard deviation was 0.03, the relative standard deviation was 0. 03%.
