Objective?To establish a high molecular exclusion chromatography (HPSEC) method for the determination of sodium cefminox polymer. Methods The efficient gel column;mobile phase (pH 7.0) 0.005mol/L phosphate buffer solution [0.005mol/L disodium hydrogen phosphate:0.005mol/L sodium dihydrogen phosphate (61∶39)];flow rate of 0.5mL/min;detection wavelength 254 nm;injection volume was 10μl;self-control external standard. Results The linear range of the sample measured 0.4-2.5mg/mL (R=0.9995). Conclusion This method can be well separated Cefminox sodium and polymers, simple, rapid, accurate, reproducible, and can be used in the polymer Cefminox sodium test.
