The importance of accurate sample preparation techniques cannot be overstated–meticulous sample preparation is essential. Often overlooked, it is the midway point where the analytes from the sample matrix are transformed so they are suitable for analysis. Even the best analytical techniques cannot rectify problems generated by sloppy sample pretreatment. Devoted entirely to teaching and reinforcing these necessary pretreatment steps, Sample Preparation Techniques in Analytical Chemistry addresses diverse aspects of this important measurement step. These include: * State-of-the-art extraction techniques for organic and inorganic analytes * Sample preparation in biological measurements * Sample pretreatment in microscopy * Surface enhancement as a sample preparation tool in Raman and IR spectroscopy * Sample concentration and clean-up methods * Quality control steps Designed to serve as a text in an undergraduate or graduate level curriculum, Sample Preparation Techniques in Analytical Chemistry also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and materials sciences.

Almost all of the breakthroughs in understanding the atmosphere have been initiated by field observations, using a range of instrumental techniques. Developing or deploying instruments to make further observations demands a thorough understanding of the chemical and spectroscopic principles on which such measurements depend. Written as an authoritative guide to the techniques of instrumental measurement for the atmospheric scientist, research student or undergraduate, Analytical Techniques for Atmospheric Measurement focuses on the instruments used to make real time measurements of atmospheric gas and aerosol composition. Topics covered include how they work, their strengths and weaknesses for a particular task, the platforms on which they have been deployed and how they are calibrated. It explains the fundamental principles upon which the instrumental techniques are based (ie what property of a molecule can be exploited to enable its detection), what limits instrumental sensitivity and accuracy, and the information that can be gained from their use.

Linking “standard” but often mutually incompatible analytical techniques – so called hyphenation – generally leads to enhanced analytical performance, so hyphenated techniques are widely used in areas where samples are presented in complex matrices, eg environmental, pharmaceutical and biochemical analysis. With these hyphenated techniques, sample preparation is often the most time-consuming step in analysis, particularly where compounds are present in low concentration, and it has a huge influence on the quality of the analytical results. Sample preparation is still not given the importance it deserves, however. The purpose of this book is to demonstrate the sample preparation chemistry that has enabled the present sensitivity, specificity and high throughput available across a range of hyphenated analytical techniques, and to illustrate the successful utilization of existing sample preparation methodologies in various analytical applications. It identifies the problems in biology, environmental science and pharmaceutical chemistry that require new ideas in chemistry and provides considered opinion on those newer techniques that may address these problems. By dealing with wider issues than is generally found in review papers, this book will provide analytical chemists with insights that are not available by searching the literature for papers on a specific topic.
