ABSTRACT Objective To establish an HPLC method for the determination of azithromycin powder.Method The chromatographic conditions were as followed: C8 column, 0.045 mol/L ammonium phosphate monobasic solution∶acetonitrile (2∶1)(adjusted to pH7.35 with triethylamine) as mobile phase, temperature: 40℃, the flow rate: 1.0 ml/min, detection wavelength: 210nm.

阿奇霉素为氮杂内酯类抗生素，日抗基和《中国药典》2005年版［1］均采用微生物检定法测定其含量，《欧洲药典》4.6版和USP26版中均采用HPLC法，专属性较强，试验周期短，但均使用的是聚合物极性柱，《欧洲药典》柱温为70℃，USP采用电化学检测器，其采用的设备在我国药检部门尚未普及［2］。

We report here on the characterization of copper-plated screen-printed electrodes modified by different clay minerals for the same purpose. The results indicated that clay minerals could improve oxidative and reductive currents of copper through the adsorption of copper ion on the surface of clay minerals. Nontronite showed the largest improvement in reductive currents of copper among the three clay minerals studied.
