Sample preparation is an essential step in many analyses. This book approaches the topic of sample preparation in chromatography in a methodical way, viewing it as a logical connection between sample collection and analytical chromatography. Providing a guide for choosing the appropriate sample preparation for a given analysis, this book describes various ways to process the sample, explaining the principle, discussing the advantages and disadvantages, describing the applicability to different types of samples, and showing the fitness to specific chromatographic determinations. The first part of the book contains an overview of sample preparation showing its relation to sample collection and...
This book reports on the first five years of research by scientists of the Tropical Soil Biology and Fertility Programme
The first edition of Chromatography: Concepts and Contrasts, published in 1988, was one of the first books to discuss all the different types of chromatography under one cover. The second edition continues with these principles but has been updated to include new chapters on sampling and sample preparation, capillary electrophoresis and capillary electrochromatography (CEC), chromatography with mass spec detection, and industrial and governmental practices in regulated industries. Covers extraction, solid phase extraction (SPE), and solid phase microextraction (SPME), and introduces mass spectrometry Updated with the latest techniques in chromatography Discusses both liquid chromatography (LC)and gas chromatography(GC)
This volume examines the assessment of higher order thinking skills from the perspectives of applied cognitive psychology and measurement theory. The volume considers a variety of higher order thinking skills, including problem solving, critical thinking, argumentation, decision making, creativity, metacognition, and self-regulation. Fourteen chapters by experts in learning and measurement comprise four sections which address conceptual approaches to understanding higher order thinking skills, cognitively oriented assessment models, thinking in the content domains, and practical assessment issues. The volume discusses models of thinking skills, as well as applied issues related to the construction, validation, administration and scoring of perfomancebased, selected-response, and constructed-response assessments. The goal of the volume is to promote a better theoretical understanding of higher order thinking in order to facilitate instruction and assessment of those skills among students in all K-12 content domains, as well as professional licensure and cetification settings.
High Throughput Bioanalytical Sample Preparation: Methods and Automation Strategies is an authoritative reference on the current state-of-the-art in sample preparation techniques for bioanalysis. This book focuses on high throughput (rapid productivity) techniques and describes exactly how to perform and automate these methodologies, including useful strategies for method development and optimization. A thorough review of the literature is included within each of these chapters describing high throughput sample preparation techniques: protein removal by precipitation; equilibrium dialysis and ultrafiltration; liquid-liquid extraction; solid-phase extraction; and various on-line techniques. T...
This sourcebook offers rare insights into a formative period in the modern history of religions. Throughout the late 19th and the early 20th centuries, when commercial, political and cultural contacts intensified worldwide, politics and religions became ever more entangled. This volume offers a wide range of translated source texts from all over Asia, the Middle East, and Europe, thereby diminishing the difficulty of having to handle the plurality of involved languages and backgrounds. The ways in which the original authors, some prominent and others little known, thought about their own religion, its place in the world and its relation to other religions, allows for much needed insight into the shared and analogous challenges of an age dominated by imperialism and colonialism.
"Alif had never set foot outside of West Sumatra. He passed his childhood days searching for fallen durian fruit in the jungle, playing soccer on rice paddies, and swimming in the blue waters of Lake Maninjau. His mother wants him to attend an Islamic boarding school, a pesantren, while he dreams of public high school. Halfheartedly, he follows his mother’s wishes. He finds himself on a grueling three-day bus ride from Sumatra to Madani Pesantren (MP) in a remote village on Java. On his first day at MP, Alif is captivated by the powerful phrase man jadda wajada. He who gives his all will surely succeed. United by punishment, he quickly becomes friends with five boys from across the archipe...
Adopting a practical approach, the authors provide a detailed interpretation of the existing regulations (GMP, ICH), while also discussing the appropriate calculations, parameters and tests. The book thus allows readers to validate the analysis of pharmaceutical compounds while complying with both the regulations as well as the industry demands for robustness and cost effectiveness. Following an introduction to the basic parameters and tests in pharmaceutical validation, including specificity, linearity, range, precision, accuracy, detection and quantitation limits, the text focuses on a life-cycle approach to validation and the integration of validation into the whole analytical quality assurance system. The whole is rounded off with a look at future trends. With its first-hand knowledge of the industry as well as regulating bodies, this is an invaluable reference for analytical chemists, the pharmaceutical industry, pharmaceutists, QA officers, and public authorities.
This book aims to provide scientists with information about a series of techniques that can be used with a view to facilitating the transformation of the sample to an appropriate state for subsequent detection or quantitation of its components of interest. The techniques dealt with range from the very simple ones (e.g. freeze-drying) to other more complex ones (e.g. glow discharge and laser-induced breakdown sampling). This is the first compilation ever on the subjects of acceleration of solid sample pretreatment; automation of solid sample pretreatment; and integration of solid sample pretreatment and detection. Readers will find here the information required to compare and select the best choice for each sample treatment need and ways to facilitate or automate the most complex and time-consuming step of the analytical process when solid samples are involved.
Scientists working or planning to work in the field of cardiovascular research will welcome Methods in Cardiovascular Research as the reference book they have been waiting for. Not only general aspects of cardiovascular research are well presented but also detailed descriptions of methods, protocols and practical examples. Written by leading scientists in their field, chapters cover classical methods such as the Langendorff heart or working heart models as well as numerous new techniques and methods. Newcomers and experienced researchers alike will benefit from the troubleshooting guide in each chapter, the extensive reference lists for advanced reading and the great practical experience of the authors. Methods in Cardiovascular Research is a "must have" for anybody with an interest in cardiovascular research.
