Gas Chromatographic Retention Indices Of Toxicologically Relevant Substances On Packed Or Capillary Columns With Dimethylsilicone Stationary Phases

International experts have compiled data on some 5000 substances (an astounding expansion compared to the 600 and 1100 substances covered in the first and second editions respectively). The enlarged data base has been made possible by combining the extended DFG-TIAFT data base with the one developed by Pfleger, Maurer and Weber. The latter has been generated mainly on capillary columns and includes many toxicologically relevant metabolites seen in actual intoxications. The more polar substances, which are difficult to chromatograph, were derivatized before retention index measurement. In addition, data on a number of important substance classes such as pesticides, beta-blockers, benzodiazepines doping agents and non-steroidal antiinflammatory drugs were considerably extended. Moreover, this new edition also covers modern capillary gas chromatography.

This is the first book to show how to apply the principles of quality assurance to the identification of analytes (qualitative chemical analysis). After presenting the principles of identification and metrological basics, the author focuses on the reliability and the errors of chemical identification. This is then applied to practical examples such as EPA methods, EU, FDA, or WADA regulations. Two whole chapters are devoted to the analysis of unknowns and identification of samples such as foodstuffs or oil pollutions. Essential reading for researchers and professionals dealing with the identification of chemical compounds and the reliability of chemical analysis.

This book brings together a number of studies which examine the ways in which the retention and selectivity of separations in high-performance liquid chromatography are dependent on the chemical structure of the analytes and the properties of the stationary and mobile phases. Although previous authors have described the optimisation of separations by alteration of the mobile phase, little emphasis has previously been reported of the influence of the structure and properties of the analyte. The initial chapters describe methods based on retention index group increments and log P increments for the prediction of the retention of analytes and the ways in which these factors are influenced by mobile phases and intramolecular interactions. The values of a wide range of group increments in different eluents are tabulated. Different scales of retention indices in liquid chromatography are described for the comparison of separations, the identification of analytes and the comparison of stationary phases. Applications of these methods in the pharmaceutical, toxicology, forensic, metabolism, environmental, food and other fields are reviewed. The effects of different mobile phases on the selectivity of the retention indices are reported. A compilation of sources of reported retention index values are given. Methods for the comparison of stationary phases based on the interactions of different analytes are covered, including lipophilic and polar indices, shape selectivity comparisons, their application to novel stationary phases, and chemometric methods for column comparisons.

Volumes in this widely revered series present comprehensive reviews of drug substances and additional materials, with critical review chapters that summarize information related to the characterization of drug substances and excipients. This organizational structure meets the needs of the pharmaceutical community and allows for the development of a timely vehicle for publishing review materials on this topic. The scope of the Profiles series encompasses review articles and database compilations that fall within one of the following six broad categories: Physical profiles of drug substances and excipients; Analytical profiles of drug substances and excipients; Drug metabolism and pharmacokinetic profiles of drug substances and excipients; Methodology related to the characterization of drug substances and excipients; Methods of chemical synthesis; and Reviews of the uses and applications for individual drug substances, classes of drug substances, or excipients. Presents comprehensive reviews covering all aspects of drug development and formulation of drugs Profiles creatine monohydrate and fexofenadine hydrochloride, as well as five others Meets the information needs of the drug development community

The analytical toxicologist may be required to detect, identify,and in many cases measure a wide variety of compounds in samplesfrom almost any part of the body or in related materials such asresidues in syringes or in soil. This book gives principles andpractical information on the analysis of drugs and poisons inbiological specimens, particularly clinical and forensic specimens. After providing some background information the book coversaspects of sample collection, transport, storage and disposal, andsample preparation. Analytical techniques - colour tests andspectrophotometry, chromatography and electro­phoresis, massspectrometry, and immunoassay – are covered in depth, and achapter is devoted to the analysis of trace elements and toxicmetals. General aspects of method implementation/validation andlaboratory operation are detailed, as is the role of the toxicologylaboratory in validating and monitoring the performance of point ofcare testing (POCT) devices. The book concludes with reviews ofxenobiotic absorption, distribution and metabolism,pharmacokinetics, and general aspects of the interpretation ofanalytical toxicology results. A clearly written, practical, integrated approach to the basicsof analytical toxicology. Focuses on analytical, statistical and pharmacokineticprinciples rather than detailed applications. Assumes only a basic knowledge of analytical chemistry. An accompanying website provides additional material and linksto related sites. Written by an experienced team of authors,Fundamentals ofAnalytical Toxicology is an invaluable resource for thosestarting out in a career in analytical toxicology across a widerange of disciplines including clinical and forensic science, foodsafety, and pharmaceutical development. Praise from the reviews: “This is an ambitious effort to describe in detail themany and varied aspects of the science of toxicological analysis.The 17 chapters cover every foreseeable aspect, from specimencollection through analytical techniques and quality control topharmacological principles and interpretation of results. Theauthors bring together a great deal of experience in the field andhave succeeded admirably in achieving their goal: "to giveprinciples and practical information on the analysis of drugs,poisons and other relevant analytes in biological specimens...".The book is very readable and quite up-to-date, and contains manyillustrative figures, charts and tables. Both the student and thepracticing professional would do well to study this materialcarefully, as there is something here for every conceivable levelof interest.” Review from RandallBaselt "This text comes highly recommended for any analyticaltoxicology trainee." The Bulletin of the Royal College ofPathologists “Overall, this book provides a comprehensive, thorough,clear, up to date and practical treatment of analytical toxicologyat a high standard. Understanding of the text is enhanced bythe use of many illustrations. Specifications, guidelines,and methods are highlighted in grey background“Boxes”. The many and up to date literaturereferences in each chapter demonstrate the authors’ thoroughwork and permit easy access to deeper information. Thereforethis book can be highly recommended as a valuable source ofknowledge in analytical toxicology both as an introduction and forthe advanced reader.” GTFCh Bulletin“Toxichem + Krimtech”, May 2008 (translated,original review in German) “Many toxicologists will add this important referenceto their libraries because it competently fills a need...” International Journal of Toxicology “The book is very well illustrated, easy to understandand pleasant to read, and contains a wealth of dedicatedinformation.” International Journal of EnvironmentalAnalytical Chemistry
