Four mechanisms were considered as possible causes of the loss in resolution for a Dionex CG2 ion chromatography resin: 1) presence of inorganic ions strongly bound to the active sites; 2) adsorption of organic species; 3) physical alterations; and 4) chemical alterations. The instrumental analyses used to gather data were ICP, FT-IR, SEM, solid C-13 NMR and IC. Based on the results, no metal ions are bound to the resin, no organic species are held onto the resin, and no physical change was observable. The cause for the loss of resolution is a strong reduction in the number of active sites in

The objective of this work has been to develop an understanding of the changes in volumetric flow rate that occur during chromatography so that flow rate measurements can be used as the basis of an analytical method. It is suggested that the total amount of gas which adsorbs on a column equals the total amount of gas which elutes from the end of the column.

The present study focuses on the development of a novel technique, namely Solids Phase Chromatography (SPC), for particle classification and size analysis. SPC is a fractionation based technique and utilises a separation channel to fractionate the particle samples into sub-fractions according to their sizes. Subsequently, the products may be analysed by various detectors and recovered for other investigations.

The aim of this study was to create a bi-layered packed bed chromatography support for the purification of nano-sized bioproducts. The effect of three different chemistry approaches, different solvent conditions, and microwave heating were investigated on construction of a bi-layered support. Sepharose CL-6B was activated with allyl glycidyl ether (routes 1&2). The inert outer layer was created in route 1 by reacting bromine with the allyl groups at the surface, followed by the addition of sodium hydroxide. Creation of the outer layer in route 2 was achieved by oxidation of surface groups with

The three factors of the resolution (Rs)equation(see Equation 1.1)were explored in this thesis. During the course of the research project, an important aim was to explore separation processes that would lead to an increase in productivity without sacrificing Rs. To that end, an increase in the retention factor (k)to enhance Rs was deemed detrimental to the cycle time, hence the production rate, particularly when preparative separations are involved. Consequently the primary objectives were to (i)prepare more efficient columns and (ii)investigate new strategies in manipulating selectivity. The

A variety of reversed phase columns were investigated using mobile phase combinations of dichlorom ethane-methanol, dichloromethane-acetonitrile, ethyl acetate-methanol and ethyl acetate-acetonitrile. Several different modes of behaviour were observed depending on the polymer solubility in the solvent system.

Instrument miniaturization is led by the desire to perform rapid diagnosis in remote areas with high throughput and low cost. In addition, miniaturized instruments hold the promise of consuming small sample volumes and are thus less prone to cross-contamination. Gas chromatography (GC) is the leading analytical instrument for the analysis of volatile organic compounds (VOCs). Due to its wide-ranging applications, it has received great attention both from industrial sectors and scientific communities. Recently, numerous research efforts have benefited from the advancements in micro-electromecha
