摘要

目的:建立凝胶高效液相色谱(HPGPC)-电雾检测器(CAD)法测定右旋糖酐40葡萄糖注射液中右旋糖酐40分子量及分子量分布,与示差检测器(RID)测定结果进行比较。方法:采用HPGPC法,TSK G4000 PWXL色谱柱(300 mm×7.8 mm,10 μm),CAD检测器流动相为甲醇-0.02 mol·L-1甲酸铵(30∶70),RIP检测器流动相为0.71%硫酸钠溶液(内含0.02%叠氮化钠),使用WATERS公司GPC软件计算分子量及分子量的分布。结果:2种方法测定右旋糖酐40分子量线性范围均为2 700~300 600,HPGPC-CAD法线性良好(r=0.997 2),精密度、稳定性、重复性试验(n=6)RSD分别为0.32%、0.23%、0.81%;HPGPC-RID法线性良好(r=0.995 4),精密度、稳定性、重复性试验(n=6)RSD分别为0.20%、0.15%、0.26%。结论:2种方法稳定、可靠,均可用于右旋糖酐40分子量及分子量分布的测定。

Abstract

Objective: To establish an HPGPC-CAD method for the determination of molecular mass and molecular mass distribution of dextran 40,and to compare the result with the HPGPC-RID method. Methods: Molecular mass and molecular mass distribution of dextran 40 were determined by HPGPC with TSK G4000 PWXL column(300 mm×7.8 mm,10 μm), and the mobile phase for HPGPC-CAD was methanol-0.02 mol·L-1 ammonium formate (30∶70). And the mobile phase for HPGPC-RID was 0.71% sodium sulfate solution, containing 0.02% sodium azide), the results were handled with the WATERS GPC software. Results: HPGPC-CAD determination showed that the linear range was 2 700-300 600 (r=0.997 2),and the precision, stability, repeatability (n=6) were 0.32%, 0.23%, 0.81%, respectively. In comparison, HPGPC-RID determination showed that the linear range was 2 700-300 600 (r=0.995 4),and the precision, stability, repeatability (n=6) was 0.20%, 0.15%, and 0.26%, respectively. Conclusion: Both HPGPC-CAD and HPGPC-RID methods are stable and reliable, and can be used for the determination of molecular mass and molecular mass distribution of dextran 40.
