Xenobiotics are chemical compounds foreign to a given biological system. In animals and humans, xenobiotics include drugs, drug metabolites, and environmental pollutants. In the environment, xenobiotics include synthetic pesticides, herbicides, and industrial pollutants. Many techniques are used in xenobiotics residue analysis; the method selected depends on the complexity of the sample, the nature of the matrix/analytes, and the analytical techniques available. This reference will help the analyst develop effective and validated analytical strategies for the analysis of hundreds of different xenobiotics on hundreds of different sample types, quickly, accurately and at acceptable cost.
Two-dimensional liquid chromatography (2D-LC) is finding increasingly wide application principally due to the analysis of mixtures of moderate to high complexity. Many industries are developing increasingly complex products that are challenging the separation capabilities of state-of-the-art 1D-LC and need new analytical methodologies with substantially more resolving power, and 2D-LC meets that need. This text, organized by two leaders in the field, establishes a sound fundamental basis for the principles of the technique, followed by a discussion of important practical considerations. The book begins with an introduction to multi-dimensional separations and a discussion of the history and development of the technique over the past 40 years, followed by several chapters that provide a theoretical basis for development of 2D-LC methods, including foundational concepts regarding separation complementarity, under-sampling, and dynamics of liquid chromatography separations. Instrumentation for 2D-LC is discussed extensively, including practical aspects such as interface selection and setup. Building on this foundation, two separate chapters are focused on method development for non-comprehensive and comprehensive separations, followed by a chapter dedicated to data analysis. Finally, applications of 2D-LC in several fields ranging from pharmaceutical analysis to polymer science are summarized. The book is an important resource for both students and practitioners who are already using 2D-LC or are interested in getting started in the field. Key Features: Demonstrates the conditions under which a 2D-LC method should be considered as an alternative to a 1D-LC method Establishes a sound fundamental basis of the principles of the technique, followed by guidelines for method optimization Provides a single source for technical knowledge advances and practical guidance described in recent literature Assists with the initial decision to develop a 2D-LC method Guides the reader in developing a high-quality method that meets the needs of their application
HPLC is the principal separation technique for identification of the pesticides in environmental samples and for quantitative analysis of analytes. At each stage of the HPLC procedure, the chromatographer should possess both the practical and theoretical skills required to perform HPLC experiments correctly and to obtain reliable, repeatable, and r
The isolation and structural characterization of substances present at very low concentrations, as is necessary to satisfy regulatory requirements for pharmaceutical drug degradants and impurities, can present scientific challenges. The coupling of HPLC with NMR spectroscopy has been at the forefront of cutting-edge technologies to address these issues. LC-NMR: Expanding the Limits of Structure Elucidation presents a comprehensive overview of key concepts in HPLC and NMR that are required to achieve definitive structure elucidation with very low levels of analytes. Because skill sets from both of these highly established disciplines are involved in LC-NMR, the author provides introductory background to facilitate readers’ proficiency in both areas, including an entire chapter on NMR theory. The much-anticipated second edition provides guidance in setting up LC-NMR systems, discussion of LC methods that are compatible with NMR, and an update on recent hardware and software advances for system performance, such as improvements in magnet design, probe technology, and solvent suppression techniques that enable unprecedented mass sensitivity in NMR. This edition features methods to quantify concentration and assess purity of isolated metabolites on the micro scale and incorporates computational approaches to accelerate the structure elucidation process. The author also includes implementation and application of qNMR and automated and practical use of computational chemistry combined with QM and DFT to predict highly accurate NMR chemical shifts. The text focuses on current developments in chromatographic-NMR integration, with particular emphasis on utility in the pharmaceutical industry. Applications include trace analysis, analysis of mixtures, and structural characterization of degradation products, impurities, metabolites, peptides, and more. The text discusses novel uses and emerging technologies that challenge detection limits as well future directions for this important technique. This book is a practical primary resource for NMR structure determination—including theory and application—that guides the reader through the steps required for isolation and NMR structure elucidation on the micro scale.
