Separation of low molecular weight ions and hydrophilic analytes is achieved by high performance ion chromatography (IC) and hydrophilic interaction liquid chromatography (HILIC). The goal of this thesis was three-fold: to increase the efficiency of IC separations by employing small particles; to develop new selectivity phases for HILIC; and to understand the factors that can lead to distorted peak shapes. Long columns packed with large polymeric particles (6.5-13 µm) still dominate IC. This
