Trends in Analytical Chemistry, Volume 3 focuses on developments in analytical chemistry, including the adoption of automation in laboratory processes, chromatography, and flow analysis. The selection first underscores the effect of automation on the operations of analytical laboratories and techniques for the automated optimization of HPLC separations. Topics include initial requirements, window diagrams, and chemometric approaches. The text then ponders on generation of statistical tables by microcomputer; enzyme electrodes for continuous in-vivo monitoring; and enantiomeric analysis of the common protein amino acids by liquid chromatography. The publication takes a look at sample preparation for the analysis of heavy metals in foods and application of ion-selective electrodes in flow analysis, including dry ashing, acid extraction, and ion-selective electrodes in flowing systems. The text then examines trends in laboratory information management systems; zone electrophoresis in open-tubular capillaries; and using computers to interpret IR spectra of complex molecules. The selection is a valuable source of data for readers interested in the developments in analytical chemistry.

This volume focuses on the most recent trends for greening analytical activities beginning with an introduction to green analytical chemistry followed by a discussion of green analytical chemistry metrics and life-cycle assessment approach to analytical method development. The chapters discuss two main topics; first is the most recent techniques for greening sample pretreatment steps, and second is modern trends for tailoring analytical techniques and instrumentation to implement the green analytical chemistry concept. The role of different kinds of green solvents, such as ionic liquids, supercritical fluids, deep eutectic solvents, bio-based solvents, and surfactants, as well as nanomaterials and green sorption materials in greening sample extraction steps is also a focus of this book. Furthermore, different approaches for greening chromatography as a key analytical technique are discussed. The applications of nanomaterials in analytical procedures are deeply reviewed, and miniaturization of spectrometers is also discussed as a recently evolved approach for efficient green on-site analysis. This book will appeal to a wide readership of academic and industrial researchers in different fields. It can be used in the classroom for undergraduate and postgraduate students focusing on the development of new analytical procedures for organic and inorganic compounds determination in different kinds of samples characterized by complex matrices composition. The book will also be useful for researchers that are interested in both chemical analysis and environment protection.

Trends in Analytical Chemistry, Volume 5 focuses on the advancements of processes, technologies, automation, and applications of analytical chemistry. The selection first offers information on graphics programming for the IBM PC using FORTRAN, PASCAL, and C, including graphics hardware system software, assembly language routines, and high level interface. The text then elaborates on the place of affinity chromatography in the production and purification of biomolecules from cultured cells and zone electrophoresis in open-tubular capillaries. Discussions focus on column and instrument design, applications, affinity chromatography in protein production from cells, and economic aspects of production and purification of proteins from cell cultures. The manuscript takes a look at polarographic and voltammetric techniques and their application to the determination of vitamins and coenzymes and activation analysis with charged particles. Topics include accelerators, principle of charged particle activation analysis, and applications. The text then examines the development of microbiological and immunological assays for antibiotics and the use of computer system for a small analytical research laboratory. The book is a dependable reference for readers interested in the trends in analytical chemistry.
