Book Synopsis Electrochemical Detection in HPLC by : Robert J Flanagan
Download or read book Electrochemical Detection in HPLC written by Robert J Flanagan and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical Detection in HPLC: Analysis of Drugs and Poisons is the first monograph devoted to the application of this mode of analysis to the assay of exogenous compounds such as drugs in biological fluids and associated areas. The introductory chapters provide information on basic electrochemistry and HPLC-ED, and on trouble-shooting. The specialized area of thiol analysis is also discussed in detail. Salient practical details of published applications of the technique in analytical toxicology and related areas are provided in a standard format. Alternative techniques are suggested throughout. The emphasis is on the analysis of exogenous compounds, although catecholamines and other endogenous species are discussed in so far as they may be used as drugs. The practical nature of this book will make it useful to professionals working in the field. It will also be of benefit to analysts wishing to use HPLC-ED in the analysis of biological samples for analytes not specifically covered in the volume.
Book Synopsis Coulometric Electrode Array Detectors for Hplc by : Ian N. Acworth
Download or read book Coulometric Electrode Array Detectors for Hplc written by Ian N. Acworth and published by VSP. This book was released on 1997 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This sixth volume in the book series Progress in HPLC-HPCE examines the enhancement of high- performance liquid chromatography through the development of an advanced mode of electrochemical detection (ECD) --- the coulometric array detection --- from its initial, yet problematic, amperometric (thin-layer) design to the highly sensitive, selective and stable coulometric (flow-through) design. Unlike amperometric electrodes, the coulometric electrode is 100% efficient and measures signals from all of the analyte passing through it, which leads to improved sensitivity as well as unique selectivity. The coulometric electrode array offers the resolution of the photodiode array with the extreme sensitivity of an electrochemical detector.
Book Synopsis Electrochemical Detectors by : T. Ryan
Download or read book Electrochemical Detectors written by T. Ryan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widely perceived utility of electrochemical detectors in High Performance Liquid Chromatography has focussed attention on a number of disparate aspects of electrochemistry related to their successful design and application. The papers in this volume deal with an extraordinarily wide range of topics but all have the common focus of electrochemical detection as a practical chromatographic tool. While it is certainly not essential to be familiar with the theoretical principles in order to utilize it successfully, the determined user of electrochemical detector will seek to have an understanding of the background. Some of the following pages will provide an excellent grounding as well as pointing the potential user in the direction of proven and possible applications in a variety of fields. The meeting, of which this book is a record, was the fifth event in the biannual Anglo-Czech Symposia in Electrochemistry. The organ izers of that meeting were extremely pleased to welcome a select group of scientists from the J Heyrovsky Institute of Physical Chemistry and Electrochemistry to the meeting, thus continuing a tradition of cooperation and friendship going back over ten years. The contributions of the visitors to the scientific content of the meeting were enthusiastically received and their participation in the informal and social activities can only have furthered the cause of cooperation and good will between our two countries.

Book Synopsis Pulsed Electrochemical Detection in High-Performance Liquid Chromatography by : William R. LaCourse
Download or read book Pulsed Electrochemical Detection in High-Performance Liquid Chromatography written by William R. LaCourse and published by Wiley-Interscience. This book was released on 1997-08-18 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: A reliable, comprehensive, relevant view of HPLC and its applications The development of HPLC-PED represents the successful marriage of two powerful analytical technologies and has resulted in the best technique for sensitive and direct detection of biological compounds with poor optical detection properties. PED has been used extensively for the determination of carbohydrates and other polar aliphatic compounds, and as a result, numerous methods have been developed to enable the analysis of a wide variety of samples. Over the years, many articles, anecdotal information, and misinformation have permeated the scientific community, with the possible consequence of confusion or uncertainty with regard to PED on the part of the analyst. Pulsed Electrochemical Detection in High-Performance Liquid Chromatography presents a reliable, comprehensive, and relevant review of HPLC-PED and its applications. The book is divided into three major parts: background material necessary for a more thorough understanding of the principles and relevance of PED; an in-depth discussion of PED using voltammetry and other electroanalytical techniques and presenting the advantages, applicability, and optimization of all existing PED waveforms; and practical aspects of HPLC-PED, including a summary of the major applications and a look at future developments in the technique. Appendices include a pulsed voltammetry (PV) program specifically written to optimize pulsed amperometric detection (PAD) waveforms and all the known applications, categorized and listed in tabular form. For analytical chemists; biochemists; carbohydrate chemists; biotechnologists; undergraduate, graduate, and postdoctoral students; and lab technicians working in a range of areas including the pharmaceutical, medical, and food and beverage industries, this eminently readable guide is the first reliable book-length treatment of how to use PED coupled with HPLC.
Book Synopsis HPLC/EC (High Pressure Liquid Chromatography/Electrochemical Detection) Studies of Selected Explosive Components, Nitroanilines, and Nitrophenols with Dual Electrode Electrochemical Detection by : D. L. Manning
Download or read book HPLC/EC (High Pressure Liquid Chromatography/Electrochemical Detection) Studies of Selected Explosive Components, Nitroanilines, and Nitrophenols with Dual Electrode Electrochemical Detection written by D. L. Manning and published by . This book was released on 1985 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dual electrode electrochemical detector has greatly enhanced high pressure liquid chromatography/electrochemical detection (HPLC/EC) capability. The most fruitful mode of operation is in the dual parallel electrode configuration. The ability to assess peak purity in real samples is very beneficial. Simultaneous recording of cathodic and anodic chromatograms to look possible impurities and munition decomposition products is an added technique to ascertain sample purity. The extent of electrode crosstalk can be minimized by repeating the experiment with the Au/Hg electrode OFF. In view of the low collection efficiencies encountered, the dual series mode of operation, at present, is of limited practical value for these types of electroactive substances.

Book Synopsis Characterization of a Microfabricated Electrochemical Detector and Coupling with High Performance Liquid Chromatography by : Evan T. Ogburn
Download or read book Characterization of a Microfabricated Electrochemical Detector and Coupling with High Performance Liquid Chromatography written by Evan T. Ogburn and published by . This book was released on 2009 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: A disposable micro-fabricated electrochemical cell has been developed, characterized with multiple electrochemical systems, and coupled with high performance liquid chromatography to form a high performance liquid chromatography electrochemical detection (HPLC-ED) system. The detection system consisted of the micro-fabricated electrochemical detector, a flow-cell and a fixture mounted with electrical connections leading from the detector to the potentiostat. The detector is easy to fabricate, inexpensive, and maintains a high performance level which makes it a practical choice for electrochemical detection. The simplicity of the fabrication process for this detector allows it to be used as a disposable device that can be replaced easily if its performance degrades. Parameters for the optimization of the performance were studied in a three-electrode system with a special focus on HPLC-ED, using ascorbic acid, acetaminophen, and potassium ferricyanide as model compounds. A separation of three pharmaceutical compounds, dextrorphan, levallorphan, and acetaminophen was also performed in order to demonstrate the performance of the novel detector in comparison to commercially available macro electrochemical detectors. It was determined that the micro-fabricated detector's performance was comparable to traditional non-disposable electrodes in these systems, especially HPLC-ED, which was the system of focus. The calibration curves constructed for each model compound showed linearity (R2> 0.99), the limit of detection reached picomolar (
