Multi-Dimensional Liquid Chromatography Principles Practice and Applications

Multi-Dimensional Liquid Chromatography Principles Practice and Applications

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 | Multi-Dimensional Liquid Chromatography Principles Practice and Applications

Introduction to Stochastic Level Crossing Techniques

Introduction to Stochastic Level Crossing Techniques

Introduction to Stochastic Level Crossing Techniques describes stochastic models and their analysis using the System Point Level Crossing method (abbreviated SPLC or LC). This involves deriving probability density functions (pdfs) or cumulative probability distribution functions (cdfs) of key random variables applying simple level-crossing limit theorems developed by the author. The pdfs and/or cdfs are used to specify operational characteristics about the stochastic model of interest. The chapters describe distinct stochastic models and associated key random variables in the models. For each model a figure of a typical sample path (realization i. e. tracing over time) of the key random variable is displayed. For each model an analytic (Volterra) integral equation for the stationary pdf of the key random variable is created−by inspection of the sample path using the simple LC limit theorems. This LC method bypasses a great deal of algebra usually required by other methods of analysis. The integral equations will be solved directly or computationally. This book is meant for students of mathematics management science engineering natural sciences and researchers who use applied probability. It will also be useful to technical workers in a range of professions. Key Features: A description of one representative stochastic model (e. g. a single-server M/G/1 queue; a multiple server M/M/c queue; an inventory system; etc. ) Construction of a typical sample path of the key random variable of interest (e. g. the virtual waiting time or workload in queues; the net on-hand inventory in inventory systems; etc. ) Statements of the simple LC theorems which connect the sample-path upcrossing and downcrossing rates across state-space levels to simple mathematical functions of the stationary pdf of the key random variable at those state-space levels Creation of (usually Volterra) integral equations for the stationary pdf of the key random variable by inspection of the sample path Direct analytic solution of the integral equations where feasible; or computational solutions of the integral equations Use of the derived stationary pdfs for obtaining operational characteristics of the model
