Selection of the HPLC Method in Chemical Analysis serves as a practical guide to users of high-performance liquid chromatography and provides criteria for method selection, development, and validation. High-performance liquid chromatography (HPLC) is the most common analytical technique currently practiced in chemistry. However, the process of finding the appropriate information for a particular analytical project requires significant effort and pre-existent knowledge in the field. Further, sorting through the wealth of published data and literature takes both time and effort away from the critical aspects of HPLC method selection. For the first time, a systematic approach for sorting through the available information and reviewing critically the up-to-date progress in HPLC for selecting a specific analysis is available in a single book. Selection of the HPLC Method in Chemical Analysis is an inclusive go-to reference for HPLC method selection, development, and validation. - Addresses the various aspects of practice and instrumentation needed to obtain reliable HPLC analysis results - Leads researchers to the best choice of an HPLC method from the overabundance of information existent in the field - Provides criteria for HPLC method selection, development, and validation - Authored by world-renowned HPLC experts who have more than 60 years of combined experience in the field

Essentials in Modern HPLC Separations, Second Edition discusses the role of separation in high performance liquid chromatography (HPLC). This new and updated edition systematically presents basic concepts as well as new developments in HPLC. Starting with a description of basic concepts, it provides important guidance for the practical utilization of various HPLC procedures, such as the selection of the HPLC type, proper choice of the chromatographic column, selection of mobile phase and selection of the method of detection, all of which are in correlation with the physico-chemical characteristics of the compounds separated. Every chapter has been carefully reviewed, with several new sections added to bring the book completely up-to-date. Hence, it is a valuable reference for students and professors in chemistry. - Provides a thoroughly updated resource, with an entirely new section on Computer-aided Method Development in HPLC and new subsections on miniaturization and automation in HPLC, chemometric aspects of HPLC, green solvent use in HPLC, and more - Includes insights into the chromatographic process to find the optimum solution for analyzing complex samples - Presents a basis for understanding the utilization of modern HPLC for applications, particularly for the analysis of pharmaceutical, biological, food, beverage and environmental samples

This volume provides a straightforward approach to isolation and purification problems with a thorough presentation of preparative LC strategy including the interrelationship between the input and output of the instrumentation, while keeping to an application focus.The book stresses the practical aspects of preparative scale separations from TLC isolations through various laboratory scale column separations to very large scale production. It also gives a thorough description of the performance parameters (e.g. throughput, separation quality, etc.) as a function of operational parameters (e.g. particle size, column size, solvent usage, etc.). Experts in the field have contributed a well balanced presentation of separation development strategies from preparative TLC to commercial preparative process with practical examples in a wide variety of application areas such as drugs, proteins, nucleotides, industrial extracts, organic chemicals, enantiomers, polymers, etc.

This book discusses in a systematic manner the role of separation in HPLC, the types and characteristics of stationary phases and of mobile phases used in this technique, as well as other factors influencing the separation. The selection process of stationary and mobile phase for a specific separation is described as related to the physico-chemical characteristics of the molecules to be separated and of their matrix. All these subjects are discussed from the point of view of the new developments in HPLC. The book also includes a part presenting the practice of modern HPLC as necessary for applications, particularly related to the analysis of pharmaceutical and biological samples, food and beverages, environmental samples, etc. Gives a clear presentation of notions and conceptsDiscusses key parameters in HPLC separationIncludes modern developments in HPLCDescribes interrelation between various HPLC features (solvent pressure, separation, detection)Includes a large number of references.
