Velocity-difference induced focusing in capillary electrophoresis and preparative capillary electrophoresis
… focusing (V-DIF) with a dynamic pH junction in capillary electrophoresis (CE) using a sample with a pH different from that of the background electrolyte (BGE) was developed in our group, but the mechanism was not well understood. In this work, the mechanism of this focusing technique was first …

Capillary supercritical fluid chromatography
The modification of a gas chromatograph for capillary supercritical fluid was demonstrated. The resulting instrument was used to characterize the performance of capillary columns manufactured specifically for SFC applications. The columns were tested for inertness, efficiency, and immobilization …

Capillary Electrophoretic Separation of Sulfoxides
… To date no work has been reported using capillary electrophoresis for the separation of alkylaryl sulfoxides. A series of alkylaryl sulfoxides were synthesized. Conditions for their separation were investigated using a modified 125 mM Boric acid (pH 8.5)/ 75 mM SDS buffer solution (MEKC …

Capillary flows in flexible structures
Interactions between capillary and elastic effects are relevant to a variety of applications, from micro- and nano-scale manufacturing to biological systems. In this thesis, we investigate capillary flows in extremely flexible, millimeter-scale cylindrical elastic tubes. We demonstrate that surface …

Modelling of capillary high harmonic generation
… of the driving laser pulse in a gas-filled capillary has a significant effect on generation. To improve the understanding of these processes, this thesis presents a spatio-temporal phasematching model for capillary HHG, and a modal-based model of laser propagation in an ionising …

Capillary rheometry of soy isolate dough
… (Promine-D) dough is determined using an Instron capillary rheometer at 298K, 333K and 363K. Thermal transitions of 10 to 100% soy isolate dough are measured using a Perkin-Elmer Differential Scanning Calorimeter (DSC-2) over 310 to 350K. The observed behavior of the soy isolate doughs is …

Development of electrochemical detection for capillary electrophoreses
… and sensitive electrochemical (EC) detection for capillary electrophoresis. To achieve this goal, electrochemical behavior of the electrolyte and analytes and the factors affecting the behavior were studied by on-line cyclic voltammetry (CV) to understand electrode response. The parameters …

Square-wave voltammetry detection for capillary electrophoresis
While the development and application of capillary electrophoresis (CE) has matured significantly in the last two decades, its application to trace analysis has been limited by The lack of a generally applicable, Sensitive detection method. This Ph.D. project's aim was to develop such a method …

Novel absorption detection techniques for capillary electrophoresis
<p>Capillary electrophoresis (CE) has emerged as one of the most versatile separation methods. However, efficient separation is not sufficient unless coupled to adequate detection. The narrow inner diameter (I. D.) of the capillary column raises a big challenge to detection methods. For UV-vis …

Capillary Liquid Chromatography Using Micro Size Particles
… with and without elevated temperatures in capillary LC is described. Very fast separations of various samples on silica-based stationary phases were achieved using optimized equipment and conditions. Great reduction in separation time, while maintaining high efficiency, is the most …
