Xenobiotics are chemical compounds foreign to a given biological system. In animals and humans, xenobiotics include drugs, drug metabolites, and environmental pollutants. In the environment, xenobiotics include synthetic pesticides, herbicides, and industrial pollutants. Many techniques are used in xenobiotics residue analysis; the method selected depends on the complexity of the sample, the nature of the matrix/analytes, and the analytical techniques available. This reference will help the analyst develop effective and validated analytical strategies for the analysis of hundreds of different xenobiotics on hundreds of different sample types, quickly, accurately and at acceptable cost.

Thin layer chromatography (TLC) is well suited for performing enantioseparations for research as well as larger-scale applications. A fast, inexpensive, and versatile separation technique, there are many practical considerations that contribute to its effectiveness. Thin Layer Chromatography in Chiral Separations and Analysis is the first book to focus solely on the theory, capabilities, and applications of TLC for direct and indirect enantioseparations. The first part of the book examines the fundamental principles of chirality and TLC. It describes the necessary materials, laboratory equipment, procedures, and strategies for the separation, quantification, isolation, and analysis of chiral compounds. The second part evaluates the real-world enantioseparations and densitometric analyses. Emphasizing pharmaceutical applications, the book discusses chiral separation mechanisms and methods for analyzing the chiral purity of diastereoisomers, amino acids, beta-blockers, and NSAIDS. Topics also include commercial stationary phases and chiral modifiers of mobile phases. Thin Layer Chromatography in Chiral Separations and Analysis presents a unified perspective of theory and experimental details underlying the collective developments in the field. The book offers scientists in a variety of disciplines and levels of expertise a complete guide to understanding the current and potential applications of chiral TLC.

The relatively new technique of solid phase microextraction (SPME) is an important tool to prepare samples both in the lab and on-site. SPME is a "green" technology because it eliminates organic solvents from analytical laboratory and can be used in environmental, food and fragrance, and forensic and drug analysis. This handbook offers a thorough background of the theory and practical implementation of SPME. SPME protocols are presented outlining each stage of the method and providing useful tips and potential pitfalls. In addition, devices and fiber coatings, automated SPME systems, SPME method development, and In Vivo applications are discussed. This handbook is essential for its discussion of the latest SPME developments as well as its in depth information on the history, theory, and practical application of the method. Practical application of Solid Phase Microextraction methods including detailed steps Provides history of extraction methods to better understand the process Suitable for all levels, from beginning student to experienced practitioner

This volume provides a straightforward approach to isolation and purification problems with a thorough presentation of preparative LC strategy including the interrelationship between the input and output of the instrumentation, while keeping to an application focus. The book stresses the practical aspects of preparative scale separations from TLC isolations through various laboratory scale column separations to very large scale production. It also gives a thorough description of the performance parameters (e.g. throughput, separation quality, etc.) as a function of operational parameters (e.g. particle size, column size, solvent usage, etc.). Experts in the field have contributed a well balanced presentation of separation development strategies from preparative TLC to commercial preparative process with practical examples in a wide variety of application areas such as drugs, proteins, nucleotides, industrial extracts, organic chemicals, enantiomers, polymers, etc.

Take your audience on a journey to leave a more lasting impact Storyshowing is an instruction manual for making connections. Storytelling has been shown to be one of the most effective methods of persuasion, motivation and inspiration, yet the disconnect remains — you're still only telling. To truly influence people, you need to go deeper than that — you need to show them your story. By inviting your audience in, you connect on a much deeper, more emotional level; you bypass the brain and connect at the root of what it means to be human, leaving a profound impact on their entire outlook. This book shows you how to transcend telling and start showing your story, using an easy-to-follow framework you can start applying today. Unearth your own experiences, and bring your vulnerabilities out into the light; share your emotions and forge a path to true communication. Use images, body language and gestures as tools to build that indelible connection; then and only then will people truly engage and transform their thinking. No matter your message, the impact lies in the delivery. This insightful guide equips you with the tools and skills you need to start communicating like never before. Share more powerful stories using a simple 5-step method Build confidence, influence others and make a deeper connection Be more persuasive in presentations, pitches, calls and talks Transform the way people think by inviting them inside your story The difference between telling and showing is like the difference between a lecture and a play. It's the difference between giving information and taking the audience on a journey. The difference between a brochure and a test drive. Storyshowing helps you level up your communication to leave a lasting, more profound impact.

There is a dramatic rise of novel drug use due to the increased popularity of so-called designer drugs. These synthetic drugs can be illegal in some countries, but legal in others and novel compounds unknown to drug chemistry emerge monthly. This thoughtfully constructed edited reference presents the main chromatographic methodologies and strategies used to discover and analyze novel designer drugs contained in diverse biological materials. The methods are based on molecular characteristics of the drugs belonging to each individual class of compounds, so it will be clear how the current methods are adaptable to future new drugs that appear in the market.
