用反相高效液相色谱法测定地塞米松磷酸钠注射液的含量系在 C18柱上,用甲醇-水(60∶40)作流动相,使用紫外检测器于254nm 处检测。本法精密度较高,重现性良好。
Determination of dexamethasone sodium phosphate injection by reversed-phase high performance liquid chromatography was performed on a C18 column using methanol-water (60:40) as the mobile phase and UV detection at 254 nm. The law of high precision, reproducibility is good.
