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.

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.

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.

Download Multidimensional Liquid Chromatographic Separations for Proteomics Book in PDF, ePub and Kindle
Sample complexity is one of the key challenges facing contemporary proteomic analysis. A variety of methods is commonly employed to reduce this complexity, both at an intact protein and digested peptide level. For complex lysates containing many thousands of proteins, orthogonal (mutually independent), multidimensional separation methods must be employed to provide sufficient resolution to characterize the appropriate number of different species. The most common of these methods are two dimensional gel electrophoresis (2DGE) of proteins and multidimensional liquid chromatographic separation (MuDPIT) of peptides, which rely on isoelectric focusing followed by mass separation in the former, and ion exchange followed by reversed phase separation in the latter. These methods have significant drawbacks in terms of sample bias, sample preparation and reproducibility, and therefore a new methodology that combines the positive aspects of both separation technologies in an automatable, reproducible form is highly desirable. New developments in column technology have allowed rapid improved-resolution separation of intact proteins in complex samples, coupled to improved methodology for peptide and protein identification. The separation of complex protein mixtures using both on- and off-line 2D liquid chromatography using derivitized polystyrene-divinylbenzene (PS-DVB) pellicular ion-exchange resins and PS-DVB monolithic reversed-phase columns is described. Proteolytic digestion of the fractions followed by rapid liquid chromatography-tandem mass spectrometry was used to complete the analysis. An alternative methodology, relying on direct analysis of the second dimension eluents by top-down (mass spectrometric analysis of intact proteins) methodology, using an Apex IV 12 T Fourier-transform ion cyclotron resonance mass spectrometer (Bruker Daltonics) and an HCT ion trap (Bruker Daltonics) equipped with electron transfer dissociation has allowed in-depth analysis of intact proteins. Sample types investigated to establish the utility of the methodology include bacterial lysates (Bordetella parapertusis, and Escherichia coli), a eukaryotic parasite (Leishmania donovani), and transformed human cell lines.
