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.

The topic is treated here in a very practical manner. The bulk of the book is concerned with real-life analyses for practising instrumentalists and differs from the literature supplied by manufacturers of atomic absorption instruments in that the methods described can be interpreted using all sorts of hardware, and in that far more chemistry and sample preparation are included.

Hank Willis Thomas gained wide recognition with his highly provocative series B(r)ANDED, which addresses the commodification of African-American male identity by raising questions about visual culture and the power of logos. Pitch Blackness, his first monograph, includes selections from this series and several others. The book begins with a deeply personal and interpretive re-telling of the senseless murder of young Songha Willis, the artist's cousin, who was robbed at gunpoint and murdered outside a nightclub in Philadelphia in 2000. It then charts Hank Willis Thomas' career as he grapples with the issues of grief, black-on-black violence in America and the ways in which corporate culture is complicit in the crises of black male identity. The concluding section presents his newest body of work, Unbranded--in which he examines advertising and media representation of African-Americans. With his characteristic pointedness and dark humor, Willis Thomas shows in Pitch Blackness why he is considered one of today's most compelling emerging artists. Essays by Rene de Guzman and Robin D. G. Kelley. Hank Willis Thomas, born in Plainfield, New Jersey in 1976, received his BFA from New York University's Tisch School of the Arts and his MFA in Photography, along with an MA in Visual Criticism from the California College of the Arts, San Francisco. He has exhibited in galleries and museums, including the Studio Museum in Harlem; Wadsworth Atheneum, Hartford; Leica Gallery, New York; and the National Portrait Gallery, Washington, D.C. Willis Thomas is the first recipient of the Aperture West Book Prize, a new annual prize awarded by Aperture Foundation. He lives in Oakland, California.

Atomic Absorption Spectrometry in Geology, Second Edition, aims to introduce geologists to the basic simplicity and applicability of atomic absorption spectrometry as it relates to geologic problems; to provide a summary of applications of atomic absorption to geology that are at scattered throughout the literature; and to encourage the accelerated application of atomic absorption spectrometry to geological problems. The book is organized into two parts. The first part, ""Theory and instrumentation,"" explains the theory of atomic absorption spectrophotometry; the operation of the atomic absorption spectrophotometer; and the types of interferences in atomic absorption spectrometry. The second part, ""Methods and applications,"" deals with applications of the atomic absorption method, including detection of the metal content of natural waters; metallic content of ores; and the analysis of trace elements in rocks and minerals. Also discussed are applications of the atomic absorption method in marine geochemistry and for isotopic abundance studies. The book includes some Appendices to the First Edition.

Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. Atomic absorption is so sensitive that it can measure down to parts per billion of a gram (μg dm-3) in a sample. The technique makes use of the wavelengths of light specifically absorbed by an element. They correspond to the energies needed to promote electrons from one energy level to another, higher, energy level. Atomic absorption spectrometry has many uses in different areas of chemistry. Examining metals in biological fluids such as blood and urine, Monitoring our environment - e.g. finding out the levels of various elements in rivers, seawater, drinking water, air, petrol and drinks such as wine, beer and fruit drink. In some pharmaceutical manufacturing processes, minute quantities of a catalyst used in the process (usually a metal) are sometimes present in the final product. By using AAS the amount of catalyst present can be determined. Many raw materials are examined and AAS is extensively used to check that the major elements are present and that toxic impurities are lower than specified - e.g. in concrete, where calcium is a major constituent, the lead level should be low because it is toxic. By using AAS the amount of metals such as gold in rocks can be determined to see whether it is worth mining the rocks to extract the gold. Atomic Absorption Spectroscopy aims to cover all major topics which are required to equip scholars with the recent advancement in this field. The book provides a systematic treatment of combining flow injection methods with all fields of atomic absorption spectrometry (AAS) including flame, hydride generation and electrothermal AAS.

"One should rather go horne and mesh a net than jump into the pond and dive far fishes" (Chinese proverb) Recognizing the precise analytical question and planning the analysis according ly is certainly the first prerequisite for successful trace and ultratrace determina tions. The second prerequisite is to select the method appropriate to the analyti cal specification. The method itself consists of a set of available tools. The third prerequisite is that analysts and operators know the methods weH enough to enjoy challenging themselves as weH as the methods and are rewarded by the joy of high-quality data, fast and economical results and the conviction of having the analytical job under control. This skill is known among analysts or operators working with an exciting new and sometimes complicated analytical technique but is gradually lost on ce a technique becomes "mature" and a routine tool. Unfortunately, laboratory managers often do not allow sufficient training time for their analysts and technicians for "routine" techniques and thus miss an opportunity for motivating their co-workers and obtaining the full benefit of the equipment. Graphite furnace atomic absorption spectrometry (AAS) is one of the mature analytical techniques wh ich is seen as a routine method in most laboratories. More than 10,000 furnaces are operated in elemental trace and ultratrace analy ses in laboratories around the world today.
