This textbook describes the theory underlying each instrumental procedure and applications of all instrumental methods. It comprehensively covers the instrumental methods of chemical analysis, chromatography, thermal methods of chemical analysis, electrochemical methods, and instrumental methods of analysis of inorganic compounds. These include thermogravimetric analysis, differential thermal analysis, thermometric titrations, and some miscellaneous thermal methods like derivative thermogravimetric analysis, thermobarography, differential scanning calorimetry, thermomechanical analysis, and electric thermal analysis, flame photometry, fluorimetry and phosphorimetry, nephelometric and turbidimetric techniques, refractory and interferometry, and X-ray methods. Each chapter consists a set of problems to aid self-learning. This textbook is highly useful for graduate and postgraduate students on chemistry and its allied fields. It can also be used as a quick reference material byprofessionals working in the various fields of chemistry and material science.
