本文采用阴离子表面活性剂作为对离子加入流动相中,控制一定pH值,在化学键合固定相色谱柱上对4种水溶性维生素进行了分离,并用内标校正曲线法定量测定了复合维B片剂中维生素含量。
In this paper, the anionic surfactant was added into the mobile phase as a counter ion to control a certain pH. Four kinds of water-soluble vitamins were separated on a chemically bonded stationary phase column. The internal standard calibration curve was used to determine the content of the composite vitamin B Vitamin content of the agent.
