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
This book addresses Furnace Atomic Absorption Spectroscopy (FAAS), which has gained worldwide acceptance as an analytical technique. FAAS offers 100-1000 times better determination and detection limits than other techniques for a majority of the elements. This technique requires a small sample size, and demands less sample-preparation time than others. The handbook is a collection of thousands of references for detection and determination of various elements in agricultural products, biological and clinical samples, and metallurgical and electronic materials. Each chapter is devoted to an element or a similar group of elements. Included are instrumental setup parameters, references, and author and subject indexes. Also presented are detailed appendixes covering glossary, list of manufacturers of spectrophotometers and its accessories, list of chemical suppliers, and list of reviews and abstracts. The handbook covers topics such as heavy metals, clinical products, and trace metal analysis. This desk-top reference is meant for chemists who handle day-to-day analysis problems in laboratories in government, clinical, industrial and academic settings. It is invaluable for those involved in research in environmental science, analytical chemistry, clinical chemistry and forensic science.

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.
