胶束动电毛细管色谱法分离测定复方感冒药帕尔克中的扑热息痛、扑尔敏、苯丙醇胺和右美沙芬４种组分。通过对缓冲液ｐＨ和ＳＤＣ浓度的优化选择，确定分离用缓冲液为２０ｍｍｏｌ／Ｌ硼酸—２０ｍｍｏｌ／Ｌ氢氧化钠溶液（ｐＨ１０，含５０ｍｍｏｌ／ＬＳＤＣ），在９ｍｉｎ内将上述４种组分完全分离且其迁移时间具有良好的重现性。 Determination of paracetamol, chlorpheniramine, phenylpropanolamine and dextromethorphan in compound cold medicine Parker by micellar electrokinetic capillary chromatography. The buffer for the separation was determined to be 20 mmol / L boric acid -20 mmol / L sodium hydroxide solution (pH 10, containing 50 mmol / L DCDC) by optimizing the buffer pH and SDC concentration, and the above four components were completely separated within 9 min And its migration time has a good reproducibility.
