Analytical Chemistry covers all the applications and techniques of molecular chemistry and it spans nearly all the areas of chemistry. This book deals with various, highly significant topics of modern, Analytical Chemistry, like analytical method validation in biotechnology today, principal component analysis, kinetic methods of examination using potentiometric and spectrophotometric detectors, the present status of Analytical Chemistry and where its future prospects lie, peptide and amino acid separations and identification, and many other related topics in this growing and expanding important area of Chemistry, in general. Analytical Chemistry has come to acquire a significantly crucial role in most, if not all, areas of scientific research today, from the recent Mars lander/rover, to underwater explorations, to forensic science to DNA characterization for dedicated medicine treatments, to climate change, and other equally important fields of modern, scientific research and development. Its application in modern -omics R&D fields has expanded so that its methods and instrumentation have gained high importance in all such areas, comprising of metabolomics, proteomics, peptidomics, combinatorial chemistry, and so forth. There will be constant growth and significance in almost all domains of modern scientific research and advancement, as well as in several areas of engineering (chemical engineering, biomedical engineering, nuclear engineering, pharmaceutical/biopharmaceutical engineering, nanotechnology, and others).this book will be of great help to chemical and industrial engineers.
