Book Synopsis Chiral Separation Using Capillary Electrophoresis (CE) and Continuous Free Flow Electrophoresis (CFFE) by :
Download or read book Chiral Separation Using Capillary Electrophoresis (CE) and Continuous Free Flow Electrophoresis (CFFE) written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, chiral separations of hydrobenzoin (HB), piperoxan (PI) and methoxyphenamine (MPA) using capillary electrophoresis (CE) are discussed. In the experimental part, separation conditions such as buffer pH, buffer concentration, CE instrumental polarity, capillary length, capillary temperature and sample matrix, etc., were considered and their impact on the chiral separations compared. All selected analytes - hydrobenzoin, piperoxan and methoxyphenamine could be well separated by CE using sulfated?-cyclodextrin (SCD) as chiral additive (CA). Preparative scale separation of MPA and PI was carried out by a continuous free flow electrophoresis (CFFE) instrument using SCD with two different degrees of substitution as CA. Rapid chiral CE methods were developed for the fractionated CFFE samples. Buffer concentration, SCD concentration, applied voltage, sample feeding rate and position, and electrode washing conditions were investigated. Experiments with dyes as surrogates were also completed on the CFFE and UV-Vis instruments. The CFFE instrument PI sample capacity was investigated using optimized conditions.

This book was released on 2012-08-29 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific monograph by the author Peter Mikus entitled "Chiral Capillary Electrophoresis in Current Pharmaceutical and Biomedical Analysis" provides a comprehensive view on the advanced capillary electrophoresis techniques aimed to current chiral bioanalysis. The advances in the chiral electrophoresis analytical approaches are divided and theoretically described in three sections involving (i) advanced chiral separations for the optimization of chiral resolution (separation mechanisms; electrophoresis techniques in capillary and microchip format; electrophoretic modes such as ITP, CZE/EKC, CEC; chiral additives / pseudophases / phases), (ii) advanced sample preparation for the on-line preconcentration, sample clean-up and analyte derivatization (implementation of electrophoretic effects such as stacking; non-electrophoretic effects such as SPE, chromatography, dialysis; combinations of these effects; multidimensional CE systems; instrumental schemes), (iii) advanced combinations of detection and electrophoresis for the optimization in qualitative and quantitative evaluation (the most important universal as well as selective detection approaches such as absorption and fluorescence spectrophotometry, electrochemical detection, mass spectrometry vs. (i) and/or (ii)). Real analytical potential (benefits and limitations) of these advanced analytical approaches is emphasized by selected performance parameters of the methods and illustrated by many current practical applications including chiral analyses of drugs, their (bio)degradation products and biomarkers in pharmaceutical and biological matrices. The author wishes the readers many inspirations in the creation of new innovative approaches in the field of advanced chiral electrophoresis techniques with the aim to overcome capabilities of the current analytical techniques.

Opening with a broad overview of chiral separations, regulatory considerations in drug product development, and basic issues in method development, the book: Covers a variety of modern methods such as gas chromatography, high performance liquid chromatography, supercritical fluid chromatography, and capillary electrophoresis Deals with the impact of chirality on the biological activity of small and large molecules Provides detailed information on useful chiral stationary phases (CSPs) for HPLC Includes handy information on selection of an appropriate CSP, including mechanistic studies Offers strategies for fast method development with HPLC, SFC, and CE Discusses preparatory methods utilized in the pharmaceutical industry With in-depth discussions of the current state of the field as well as suggestions to assist future developments, Chiral Separation Methods for Pharmaceutical and Biotechnological Products is an essential text for laboratory investigators, managers, and regulators who are involved in chiral separations in the pharmaceutical industry, as well as students preparing for careers in these fields.
Book Synopsis Design of Chiral Separations by Liquid Chromatography and Capillary Electrophoresis for Amlodipine and Derivatives by : Tracy Sharon Small
Download or read book Design of Chiral Separations by Liquid Chromatography and Capillary Electrophoresis for Amlodipine and Derivatives written by Tracy Sharon Small and published by . This book was released on 1995 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of chiral separations in liquid chromatography (LC) and capillary electrophoresis (CE) involves the selection of chiral selectors and eluent parameters, often on a purely empirical basis. It would be desirable if rapid screening methods could be designed to rationalise the choice of these chiral selectors. With reference to the use of cyclodextrin (CD) derivatives as chiral selectors, nuclear magnetic resonance spectroscopy (NMR) can play an important role in screening the extent of interactions with chiral solutes, and in probing the nature of the stereoselective interactions involved. Data from high-field NMR on drugs and their derivatives have been explored for screening a number of potential chiral recognition agents, as an aid to the rational design of chiral separations by LC and CE, based on cyclodextrins (alpha, beta, gamma, hydroxypropyl-beta and hydroxyethyl-beta) bonded to silica (LC) and in free solution (CE). In this investigation high-field FT-NMR is used to examine the interaction mechanism between these cyclodextrins and the calcium channel blocker Amlodipine together with a series of its structural analogues. Enantiomeric interactions between the cyclodextrins and Amlodipine are explored using ROESY (rotating frame nuclear Overhauser effect spectroscopy) in order to determine the inclusion mechanism involved......

This book was released on 2010-06-16 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: What drives a scientist to edit a book on a speci c scienti c subject such as chiral mechanisms in separation methods? Until December 2005, the journal Analytical Chemistry of the American Chemical Society (Washington, DC) had an A-page section that was dedicated to simple and clear presentations of the most recent te- niques or the state of the art in a particular eld or topic. The “A-page” section was prepared for a broad audience of chemists including industrial professionals, s- dents as well as academics looking for information outside their eld of expertise. 1 Daniel W. Armstrong, one of the editors of this journal and a twenty-year+ long friend, invited me to present my view on chiral recognition mechanisms in a simple and clear way in an “A-page” article. In 2006, the “A-page” section was maintained as the rst articles at the beginning of each rst bi-monthly issue but the pagination was no longer page distinguished from the regular research articles published by the journal. During the time between the invitation and the submission, the A-page section was integrated into the rest of the journal and the article appeared as (2006) Anal Chem (78):2093–2099.
