Despite the existence of many competitive analytical techniques, molecular absorption spectrophotometry still remains very popular in practice, particularly in biochemical, clinical, organic, agricultural, food and environmental analyses. This is due mainly to the inherent ease and relative simplicity of spectrophotometric procedures and the availability of reliable and highly-automated instruments. Moreover, the method and its instrumentation has recently undergone considerable development resulting in some new special approaches of spectrophotometry in the ultraviolet (UV) and visible (VIS) regions. Although there are a number of comprehensive textbooks dealing with UV/VIS spectrophotometry, they tend to describe historical aspects or contain collections of detailed procedures for the determination of analytes and do not reflect sufficiently the present state of the method and stage of development reached. This book provides a concise survey of the actual state-of-the-art of UV/VIS spectrophotometry. Special attention has been paid to problems with the Bouguer-Lambert-Beer law, absorption spectra, present trends in instrumentation, errors in spectrophotometry, evaluation of analyte concentration and calibration, optimization procedures, multicomponent analysis, differential spectrophotometries, problem of blanks, derivative and dual-wavelength spectrophotometry, spectrophotometric titration, the strong relations between complex formation and spectrophotometry, spectrophotometric investigation of complex equilibria and stoichiometry or automation in spectrophotometry. The significance of spectrophotometry in connection with liquid-liquid extraction, reaction kinetics, trace analysis, environmental and clinical analysis is also covered. The text is supported by tables and figures, and numerous references are provided for each topic treated. The book is written for all those who use UV/VIS spectrophotometry in the laboratory and will also be useful to students as supplementary reading.

Spectrophotometry enables one to determine, with good precision and sensitivity, almost all the elements present in small and trace quantities of any material. The method is particularly useful in the determination of non-metals and allows the determination elements in a large range of concentrations (from single % to low ppm levels) in various materials. In Separation, Preconcentration and Spectrophotometry in Inorganic Analysis, much attention has been paid to separation and preconcentration methods, since they play an essential role in increasing the selectivity and sensitivity of spectrophotometric methods. Separation and preconcentration methods have also been utilised in other determination techniques. Spectrophotometric methods which are widely used for the determination of the elements in a large variety of inorganic materials are presented in the book whilst separation and preconcentration procedures combined with spectrophotometry are also described. This book contains recent advances in spectrophotometry, detailed discussion of the instrumentation, and the techniques and reagents used for spectrophotometric determination of elements in a wide range of materials as well as a detailed discussion of separation and preconcentration procedures that precede the spectrophotometric detection.

PRINCIPLES OF INSTRUMENTAL ANALYSIS is the standard for courses on the principles and applications of modern analytical instruments. In the 7th edition, authors Skoog, Holler, and Crouch infuse their popular text with updated techniques and several new Instrumental Analysis in Action case studies. Updated material enhances the book's proven approach, which places an emphasis on the fundamental principles of operation for each type of instrument, its optimal area of application, its sensitivity, its precision, and its limitations. The text also introduces students to elementary analog and digital electronics, computers, and the treatment of analytical data.

Spectrophysics covers those applications of spectroscopy that are directed at investigating the interactions or radiating atoms and molecules with their environment, with particular reference to the fields of astrophysics, plasma physics and atmospheric physics. Much of the material is normally found only in specialized texts.
