| Summary: | Charles University, Faculty of Pharmacy in Hradec Králové Department of Analytical Chemistry Candidate: Mgr. Kateřina Plachká Supervisor: prof. Pharm.Dr. Lucie Nováková, Ph.D. Title of Doctoral Thesis: The development of new methods of ultra-high performance supercritical fluid chromatography for pharmaceutical applications A compilation of seven articles and three book chapters dealing with the applicability of supercritical fluid chromatography (SFC) methods in the field of pharmaceutical analysis is presented in this dissertation thesis. The first part focuses on pharmaceutical quality control and especially impurity control. The presented articles are dealing with the searching for generic screening approach for the development of SFC methods and with the subsequent optimization and validation of these methods. The screening conditions were compared based on developed mathematical model. The generic combination of diol stationary phase and 0.1 % ammonium hydroxide in methanol as modifier of CO2-based mobile phase was proposed as a starting point for SFC method development based on the obtained results. Several challenges were described during optimization of UHPSFC methods and their solution was proposed. The benefits of acetonitrile added to the modifier, advantages of column coupling and the... |
