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.

Download or read book Fundamentals of Ambient Metastable induced Chemical Ionization Mass Spectrometry and Atmospheric Pressure Ion Mobility Spectrometry written by Glenn A. Harris and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular ionization is owed much of its development from the early implementation of electron ionization (EI). Although dramatically increasing the library of compounds discovered, an inherent problem with EI was the low abundance of molecular ions detected due to high fragmentation leading to the difficult task of the correct chemical identification after mass spectrometry (MS). These problems stimulated the research into new ionization methods which sought to "soften" the ionization process. In the late 1980s the advancements of ionization techniques was thought to have reached its pinnacle with both electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). Both ionization techniques allowed for "soft" ionization of large molecular weight and/or labile compounds for intact characterization by MS. Albeit pervasive, neither ESI nor MALDI can be viewed as "magic bullet" ionization techniques. Both techniques require sample preparation which often included native sample destruction, and operation of these techniques took place in sealed enclosures and often, reduced pressure conditions. :New open-air ionization techniques termed "ambient MS" enable direct analysis of samples of various physical states, sizes and shapes. One particular technique named Direct Analysis In Real Time (DART) has been steadily growing as one of the ambient tools of choice to ionize small molecular weight (

In each of these cases, the combination of the two techniques provided the information necessary to address the analytical problem.
Download or read book Extending Atmospheric Pressure Mass Spectrometry written by Kevin Turney and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During desorption process in MALDI, a large population of neutral molecules is created. A secondary ionization technique, such as atmospheric pressure chemical ionization, can provide reagent ions for interaction with laser desorbed neutrals. Results show that UV laser desorbed neutrals do interact with atmospheric pressure reagent ions; however, the individual optimization of each process is needed. Secondary ionization of the neutral molecules provides an avenue for probing ion-molecule chemistry. The exploitation of AP interfaces with atmospheric pressure laser desorption techniques can provide needed advances in biological analysis.
