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

This book addresses the growing interest in the field of two-dimensional liquid chromatography (2DLC), a powerful approach to increasing resolution, available peak capacity, and selectivity in analytical chromatography. 2DLC is suitable for many applications, including in the pharmaceutical and polymer industries and the omic sciences (metabolomics, lipidomics and proteomics). Thanks to recent advances in technology and software the instrumentation needed to perform 2D-LC is broadly available to the analytical community in both industry and academia. Indeed, the technique can now be considered ready for application in R&D as well as in QA and QC labs, yet it is not widely known about outside academic laboratories and is rarely taught at the undergraduate level. This book outlines the main principles and features of 2D-LC (including comprehensive and heart-cutting modes, method development and real world applications) to enable modern analysts to start using this fascinating technique. The book offers an ideal starting point for those wishing to get into 2D-LC and will also be of interest to more experienced scientists in the field.

This book presents the principle ideas of combining different analytical techniques in multi-dimensional analysis schemes. It reviews the basic principles and instrumentation of multi-dimensional chromatography and the hyphenation of liquid chromatography with selective spectroscopic detectors and presents experimental protocols for the analysis of complex polymers. It is the consequent continuation of "HPLC of Polymers" from 1999 by the same authors. Like its 'predecessor', this book discusses the theoretical background, equipment, experimental procedures and applications for each separation technique, but in contrast treats multi-dimensional and coupled techniques. "Multidimensional HPLC of Polymers" intends to review the state of the art in polymer chromatography and to summarize the developments in the field during the last 15 years. With its tutorial and laboratory manual style it is written for beginners as well as for experienced chromatographers, and will enable its readers (polymer chemists, physicists and material scientists, as well as students of polymer and analytical sciences) to optimize the experimental conditions for their specific separation problems.

Many mixtures important to research consist of hundreds or even thousands of individual components of interest. These types of mixtures are far too complex to separate by a single chromatographic dimension in any reasonable amount of time. However, if a multidimensional approach is used, where a complex mixture is separated by an initial dimension, simpler fractions of that separation are collected and each of those fractions are analyzed individually, highly complex mixtures can be resolved in relatively short amounts of time. This dissertation serves as a guide to multidimensional chromatography, in particular, two-dimension liquid chromatography. There are many aspects of multidimensional separations that have been investigated to show its aspects, drawbacks and potential ability to separate highly complex mixtures. Measurements for the performance of multidimensional chromatography, the effects of the first and subsequent dimensions and the approaches to pairing dimensions are shown with experimental examples. Fundamental and practical features of multidimensional chromatography are explained as well as theoretical discussions on current and future multidimensional chromatography performance. Experimentally, very high peak capacities were obtained (ca. 7000) and an algorithm to predict how to best optimize a two-dimensional separation based on the time used and performance was created for designing experiments.

Multidimensional Analytical Techniques in Environmental Research is a comprehensive resource on the many multidimensional analytical strategies to qualitatively and quantitatively assess and map the organic and inorganic pollutants in complex atmospheric, water and soil matrices. During the past two decades, the rapidly-evolving field of analytical instrumentation has produced sophisticated multidimensional tools capable of providing unique and in-depth knowledge on the chemical features of complex mixtures from these different environmental matrices. This book brings together the wealth of information in the current literature, assisting in the decision-making process by covering both the fundamentals and applications of these methodologies. Sections cover the wide variety of multidimensional analytical techniques, including multidimensional solution- and solid-state nuclear magnetic resonance (NMR) spectroscopy, ultrahigh-resolution mass spectrometry (MS), two-dimensional correlation spectroscopy, two-dimensional liquid and gas chromatography and capillary electrophoresis coupled to high-resolution detection techniques, and excitation-emission (EEM) fluorescence spectroscopy assisted by multiway data analysis tools, and the use of synchrotron-radiation-based techniques combined with other spectroscopic approaches to explore and map the speciation of elements. - Identifies state-of-the-art multidimensional analytical methods for targeted and untargeted profiling of complex mixtures from different environmental matrices (soil, sediment, water, and air) - Assesses the advantages and limitations of the most modern and sophisticated multidimensional analytical methods in environmental research - Highlights the current challenges and potential future directions in the application of multidimensional analytical tools to advance the current understanding on the dynamics and fate of environmental pollutants in different environmental matrices

Food manufacturers, researchers and society in general are becoming very interested in the quality, integrity and safety of food products. Within this context, and considering the complexity of the food chain in a globalized world where many players are involved between the production and consumption of a food product, together with the possible ways of food contamination such as environmental, agrochemical and food manipulation (packaging) sources, fast and reliable analytical methodologies to guarantee food quality, integrity and safety are required.Mass spectrometry therefore plays a relevant role in this field to satisfy the demands of sensitivity and selectivity for the analysis of complex food samples. In this book, new advances in mass spectrometry techniques in food analysis, involving their hyphenation with chromatographic and related separation techniques, as well as relevant applications reporting the determination of polyphenols, pesticides, mycotoxins, lipids, and peptides among other compounds, will be addressed.
