Book Description
Studies in Analytical Chemistry, Volume 4: Guide-Lines to Planning Atomic Spectrometric Analysis covers the physico-chemical background of atomic absorption spectrometry (AAS) and atomic emission spectrometry (AES). This book is composed of six chapters and begins with an introduction to the criteria on choosing the best and most suitable method for solving a given analytical problem. The next chapters deal with the properties, generation, and absorption of electromagnetic radiation, as well as the theory of atomic spectra that require knowledge of X-ray. Other chapters discuss the broadening of atomic lines, which is important for understanding that calibration curves in AAS are always bent. A chapter examines the sensitivity of determination by AAS and AES. The last chapter describes the spectrometric measurement of atomic absorption and emission. This chapter also looks into the influence of the design of the monochromator upon the measured emission intensity and calibration curve by AAS. This book will prove useful to analytical chemists and researchers.

Book Description
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.

Book Description
Solvation, Ionic and Complex Formation Reactions in Non-Aqueous Solvents: Experimental Methods for their Investigation presents the available methods and their particular value in investigating solutions composed of non-aqueous solvents. This book is composed of 10 chapters and begins with a brief description of the complexity of the interactions possible n solutions. The subsequent chapters deal with a classification of the solvents and empirical solvent strength scales based on various experimental parameters, together with various correlations empirically describing the solvent effect. Other chapters present the methods for the purification of solvents and ways of checking their purity, as well as the individual results achieved during investigations of the solvent effect, particularly the general regularities recognized. The remaining chapters provide a review of the coordination chemistry of non-aqueous solutions. This book will prove useful to analytical and inorganic chemists.

Book Description
The thoroughly revised new edition of this best-seller, presents the wide use of AAS in numerous fields of application. The comparison between the different AAS techniques enables the reader to find the best solution for his analytical problem. Authors Bernhard Welz and Michael Sperling have succeeded in finding a balance between theoretical fundamentals and practical applications. The new chapter 'physical fundamentals' describes the basic principles of AAS. The development of AAS is now described in a separate chapter. Further new chapters are devoted to the latest developments in the field of flow injection and the use of computers for laboratory automation. Methodological progress e. g. speciation analysis is also covered in this new edition. The index and the extensive bibliography make this book a unique source of information. It will prove useful not only for analytical chemists, out also spectroscopists in industry, institutes, and universities. Atomic Absorption Spectrometry will also be invaluable for clinics and research institutes in the fields of biochemistry, medicine, food technology, geology, metallurgy, petrochemistry, and mineralogy.
