用高效液相色谱法 ,于氯己定有特征吸收峰且干扰较小的 2 53nm波长下测定溶液中氯己定含量。对氯己定含量≤ 0 4 2 2 2mg/ml的溶液 ,测定结果的相对偏差≤ 1 4 %。
High performance liquid chromatography, chlorhexidine has a characteristic absorption peak and less interference at a wavelength of 2 53nm determination of chlorhexidine solution. For chlorhexidine content ≤ 0 4222mg / ml solution, the relative deviation of the determination results ≤ 14%.
