目的:建立以反相高效液相色谱法测定头孢噻肟钠含量的方法。方法:色谱柱为ultimate-C18,流动相为1.0 g.L-1的三乙量胺水为2溶0液μ(L用。磷结酸果调:p头H孢值噻至肟6.2钠)在-2.甲7醇×1(608-∶63～20.)0,2流0速7 g为.1L.0-1(mrL=.0m.i9n9-91 9,检)的测范波围长为内2线54性n关m,系柱良温好:25,检℃出,限流速为9为×11.00-9m gL..Lmi-1n-1,RS,进D=样0.18%。结论:所建立的方法分析速度快、灵敏度高,可用于头孢噻肟钠产品的含量测定。
Objective: To establish a method for the determination of cefotaxime sodium by reversed-phase high performance liquid chromatography. Methods: The amount of triethylamine in water with the mobile phase of 1.0 gL-1 as the ultimate-C18 and the mobile phase of 1.0 g L-1 was -2. A 7 alcohol × 1 (608-: 63 ~ 20.) 0,2 flow 0 speed 7 g is .1L.0-1 (mrL = .0m.i9n9-91 9, seized) measurement range Wai Length of 2 lines 54 n-off m, the Department of good column temperature: 25, check out, the limit flow rate of 9 × 11.00-9m gL..Lmi-1n-1, RS, into the D = like 0.18%. Conclusion: The established method has the advantages of fast analysis and high sensitivity, and can be used for the determination of cefotaxime sodium product.
