dc.description.abstract The main focus of this dissertation is on the development of new chiral stationary phases for HPLC and GC and the application of ionic liquids in analytical chemistry . They will be discussed separately in two parts . Enantiomeric separations continue to be of great interest to the pharmaceutical industry . It is because drug molecules of opposite chirality often possess distinctive effects in biological environments . Direct chromatography is one of the major techniques used to address the challenge of enantiomeric analysis . Macrocyclic glycopeptides are a very useful class of chiral selectors for HPLC stationary phases because of their broad enantioselectivity . A study of a new macrocyclic glycopeptide antibiotic , dalbavancin , as chiral selector for HPLC will be described in part one . Two stationary phases based on dalbavancin were synthesized via two different binding strategies and compared against with commercial teicoplanin column . The application of Ionic liquids in analytical chemistry is growing rapidly due to their valuable properties such as wide liquid temperature range , high thermal stability , inflammability etc . Several techniques based on ionic liquids are maturing into commercialized products . In part two , the synthesis , physical properties , and the use as ion pairing reagent for anion detection in ESI -MS of linear tricationic ionic liquids will be presented . In chapter 7 , a study of new chiral GC columns using ionic liquids as matrices and methylated ionic cyclodextrin as chiral selector will be discussed . en_US
