Rational method development strategies on a fluorinated liquid chromatography stationary phase: mobile phase ion concentration and temperature effects on the separation of ephedrine alkaloids.
J. Chromatogr. A. 1095(1-2) , 113-8, (2005) Fluorinated, silica-based stationary phases are becoming increasingly popular alternatives to traditional alkyl phases owing to their differential selectivity and retention for a variety of analyte classes. In this report, the ion-exchange mechanisms characte... |
