| 摘 要： | 关于枸椽酸镓-67注射液放化纯度的鉴定,文献已有报道。Hnatowich比较了几种展开剂对不同形式镓的R_f值的影响;Waxmax用甲醇-水的硅胶薄板色层法对几种枸椽酸镓-67商业产品作了放化纯分析,日本是采用柠檬酸钠-乙醇展开剂的纸色层分析法。 本文比较了五种展开剂在中性产品条件下及三种展开剂在不同pH值条件下对不同形式镓的纸色层图谱的影响,试图选择1-2种展开剂作为生产枸椽酸镓-67注射液放化纯的常规鉴定方法。

| Abstract: | A simple method is used to compare the effect of five developing agents on the radio-chemical purity of neutral products of 67GaCit and on Rf values. Two preferable developing agents are recommended as suitable for the identification of 67GaCit injection in its production. The effect of six pH values of different developing agents on radiochemical purity, Rf and chromatogram are compared for the neutral products. The results of the experiments show that the ascending paper chromatography with 1:2:4 pyridine/ethanol/ water and 85:15 methanol/water is preferable for the determination of the radiochemical purity of 67GaCit. The other developing agents also can be used if there are not any impurities except gallium radioisotopes. |
