Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the progress and accomplishments of this research project from September 1, 1989 to February 28, 1993. During this period, we have accomplished all of the primary scientific objectives of the research proposal: (1) constructed and evaluated a laser-induced fluorescence detection system that allows direct examination of the chromatographic column, (2) examined nonequilibrium processes that occur upon solute injection and elution, (3) examined solute retention in liquid chromatography as a function of temperature and pressure, (4) examined solute zone dispersion in liquid chromatography as a function of temperature and pressure, and (5) developed appropriate theoretical models to describe these phenomena. In each of these studies, substantial knowledge has been gained of the fundamental processes that are responsible for chromatographic separations. In addition to these primary research objectives, we have made significant progress in three related areas: (1) examined pyrene as a fluorescent polarity probe insupercritical fluids and liquids as a function of temperature and pressure, (2) developed methods for the class-selective identification of polynuclear aromatic hydrocarbons in coal-derived fluids by microcolumn liquid chromatography with fluorescence quenching detection, and (3) developed methods for the determination of saturated and unsaturated (including omega-3) fatty acids in fish oil extracts by microcolumn liquid chromatography with laser-induced fluorescence detection. In these studies, the advanced separation and detection techniques developed in our laboratory are applied to practical problems of environmental and biomedical significance.

This book was released on 2023-01-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text aims to evaluate the actual impact of high-performance capillary electrophoresis on analytical biotechnology and environmental analysis. The first part of the book presents a survey of present innovations in instrument design and different methods of pre-concentration techniques in order to obtain increased separations at higher sensitivities. The second part contains articles on applications of HPCE to protein and peptide analysis. In the third part, applications of HPCE in the investigation of drug abuse and drug interactions are presented. The last two parts of the book deal with the use of HPCE at low-UV wavelengths and negative-UV absorption. The book should be of interest to those working in HPCE research and applications.

This book was released on 1996 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary zone electrophoresis (CZE), a powerful separation method based on the differential migration of charged species under the influence of an electric field, has been widely used for separations covering from small ions to big biomolecules. Chapter 1 describes the method, then discusses detection of the separated analytes by laser induced fluorescence and by chemical derivatization, and the use of O-phthaldialdehyde (OPA) as a post-column reagent. Chapter 2 describes a post-column reactor which uses two narrow bore capillaries connected coaxially. This reactor differs from other coaxial reactors in terms of capillary dimensions, reagent flow control, ease of construction and most importantly, better limits of detection. The derivatization reagent is electroosmotically driven into the reaction capillary and the reagent flow rate is independently controlled by a high voltage power supply. Amino acids, amines and proteins, derivatized by OPA/2-mercaptoethanol using this post-column reactor coupled with LIF detection, show low attomole mass limits of detection, and for the first time, the authors demonstrate single cell capability with a post-column derivatization scheme. The single cell capability shows that this reactor could find applications in assaying non-fluorescent or electrochemically inactive components in individual biological cells in the future.

This book was released on 2000 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planar microfluidic devices may provide a powerful tool for automating the fluid handling steps required in many biological assays and offer an alternative to biosensors for detection of biological threat agents. This paper describes a highly sensitive laser induced fluorescence (LIF) detection system based on a laser diode and cyanine-5 dye for use with a planar, microfluidic, capillary electrophoresis (CE) chip. The capabilities of the CE-chip to determine a protein biological threat agent simulant by performing an immunuoassay separation are described along with the optimal parameters needed to obtain good detection limits with a confocal, epiluminescent detection system utilizing a photomultiplier tube.
