This book was released on 2006 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capillary electrophoresis offers faster analysis times and higher efficiencies than many chromatographic techniques (e.g., high performance liquid chromatography). Various capillary electrophoretic techniques were investigated in an attempt to develop a fast and easy method for the analysis of neutral compounds found in smokeless powder, i.e., diphenylamine (DPA), ethylcentralite (EC), and trinitrotoluene (TNT). The need to produce such a method is of great importance in forensic science where high-throughput analyses are needed. Capillary zone electrophoresis (CZE), micellar electrokinetic chromatography (MEKC), and non-aqueous capillary electrophoresis (NACE) techniques were evaluated. A Hewlett Packard 3D-CE instrument was utilized for all analyses. DPA was undetected employing CZE and MEKC due to its insolubility in an aqueous environment. NACE, a relatively new and under-developed technique, was ultimately chosen to achieve maximum sensitivity and overcome potential compound insolubility problems. Secondarily, the influence of the acetate ion (rather than the commonly suggested ammonium ion) on the separation of neutral compounds, and the usage of traditional CZE electroosmotic flow (EOF) markers in NACE were both investigated. It was determined that the acetate ion does significantly influence NACE separation of the selected neutral compounds, and traditional CZE EOF markers do not accurately measure EOF in NACE as suggested in literature. It was also found that the use of organic solvents (i.e., methanol and acetonitrile) and ammonium acetate in NACE may cause irreversible aging of the capillary, resulting in increased analysis times and peak broadening.
Book Synopsis Handbook of Capillary Electrophoresis by : James P. Landers
Download or read book Handbook of Capillary Electrophoresis written by James P. Landers and published by CRC Press. This book was released on 1994 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Capillary Electrophoresis is a valuable collection of in-depth discussions of specific areas of capillary electrophoresis (CE) that are key to the practical use of CE for sample analysis. The handbook is divided into five parts. Part I focuses on various modes of CE that have been developed and applied to analytical/separation problems. Part II covers detection in CE, with one section reviewing all detector systems that have been successfully interfaced with CE and another that focuses on CE-mass spectrometry. Part III explores how CE can be applied to the analysis of a specific class of molecules/analytes or to solving separation problems. CE analysis of organic ions, pharmaceuticals, glycoconjugates, peptides, proteins, and DNA fragments; the components of single cells; and the utility of capillary coatings in CE are all covered in this section. A key element of this handbook is its discussion of the potential role of CE for solving clinical problems and the potential for CE and CE-MS to advance analysis of drug metabolism. The handbook also presents practical and theoretical discussions on various aspects of CE, including sample matrix and its effects on separation, the need for controlling capillary temperature, and the present and future implications of EOF control. In-depth discussions of this nature comprise Parts IV and V. The Handbook of Capillary Electrophoresis will be an outstanding reference for analytical chemists, biochemists, clinical chemists, cell biologists, and pharmaceutical researchers.

Book Synopsis Capillary Electrophoresis Guidebook by : Kevin D. Altria
Download or read book Capillary Electrophoresis Guidebook written by Kevin D. Altria and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to be a working guide to the operation of capillary electrophoresis (CE) instrumentation. Since CE is still a rap idly maturing technique, detailed validated protocols are not widely established. Therefore, extensive experimental procedures are not pro vided for individual analyses. The intention is to provide general guide lines on the principles and practice of CE and to give an overview of the specific technologies and important application areas. Part I provides operating instructions for standard commercially available instruments. Guidelines are included for activities such as changing capillaries, method development, quantitative procedures, optimization of precision and sensitivity, and the validation of meth ods, fraction collection, and troubleshooting, as well as a quick guide to running a separation. The application range of CE is possibly the most diverse of all analytical techniques and ranges from large, complex macromolecules, such as proteins and nucleic acids, to small solutes, such as organic drugs and inorganic anions and cations.

Book Synopsis Clinical Applications of Capillary Electrophoresis by : Stephen M. Palfrey
Download or read book Clinical Applications of Capillary Electrophoresis written by Stephen M. Palfrey and published by Springer Science & Business Media. This book was released on 2008-02-01 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Clinical Applications of Capillary Electrophoresis, Stephen Palfrey brings together for first time a collection of detailed capillary electrophoresis protocols designed exclusively for clinical applications. Written by the leading scientists who have often perfected these methods in their own laboratories, the protocols furnish new and more powerful assays for many routine serum and blood tests now regularly performed in clinical laboratories, including urine protein analysis, hemoglobin separation, and the detection of CSF proteins, lipoproteins, myoglobin, cryoglobulins, HbA1c, and cathepsin. The protocols offered for DNA studies include double-stranded DNA analysis, the prenatal diagnosis of Down's syndrome, Rh D/d genotyping, the identification of mutated p53 oncogene, and the detection of microsatellite instability in cancers. Many of the methods can be automated to replace the more costly and labor-intensive tests that are currently used in most clinical laboratories. Clinical Applications of Capillary Electrophoresis demonstrates clearly the simplicity, versatility, and power of CE over conventional methods. It offers to beginning clinical investigators, as well as established laboratories new to the technique, a representative range of highly practical CE methods-assays that are not only certain to become ever more productive, but are already eminently useful today.
