Handbook of Sample Preparation
Discover new keys to solving analytical problems using the Latest sample preparation methods Commonly viewed of as a routine task rather than as an integral component in the analytical process, sample preparation has long been undervalued as a science and underdeveloped as a technology. In an effort to reverse this trend, Handbook of Sample Preparation shows why sample preparation deserves closer scientific scrutiny, and makes a compelling case for colleges and professional laboratories to devote more resources to promote the benefits of its correct application. Handbook of Sample Preparation includes: A solid overview of standard sampling methodologies and their analytical capabilities An introduction of non-traditional sampling technologies, which address the need for solvent-free alternatives, automation, and miniaturization A discussion of the analytical shift toward performing sampling on-site, rather than in the laboratory An examination of various extraction technologies and their applications for different types of matrices A look at how to take advantage of new sampling strategies to streamline laboratory procedures, reduce research costs, and increase overall productivity An excellent primer on the fundamentals of extraction as well as a sound guide on the latest technological upgrades influencing current sampling techniques, this versatile text serves as an important and accessible tool for both students and seasoned practitioners as they seek new avenues for improving the accuracy of their analyses.
Sample Preparation Handbook for Transmission Electron Microscopy

Successful transmission electron microscopy in all of its manifestations depends on the quality of the specimens examined. Biological specimen preparation protocols have usually been more rigorous and time consuming than those in the physical sciences. For this reason, there has been a wealth of scienti?c literature detailing speci?c preparation steps and numerous excellent books on the preparation of b- logical thin specimens. This does not mean to imply that physical science specimen preparation is trivial. For the most part, most physical science thin specimen pre- ration protocols can be executed in a matter of a few hours using straightforward steps. Over the years, there has been a steady stream of papers written on various aspects of preparing thin specimens from bulk materials. However, aside from s- eral seminal textbooks and a series of book compilations produced by the Material Research Society in the 1990s, no recent comprehensive books on thin spe- men preparation have appeared until this present work, ?rst in French and now in English. Everyone knows that the data needed to solve a problem quickly are more imp- tant than ever. A modern TEM laboratory with supporting SEMs, light microscopes, analytical spectrometers, computers, and specimen preparation equipment is an investment of several million US dollars. Fifty years ago, electropolishing, chemical polishing, and replication methods were the principal specimen preparation me- ods.
Sample Preparation Techniques in Analytical Chemistry
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.
