Provides students and practitioners with a comprehensive understanding of the theory of spectroscopy and the design and use of spectrophotometers In this book, you will learn the fundamental principles underpinning molecular spectroscopy and the connections between those principles and the design of spectrophotometers. Spectroscopy, along with chromatography, mass spectrometry, and electrochemistry, is an important and widely-used analytical technique. Applications of spectroscopy include air quality monitoring, compound identification, and the analysis of paintings and culturally important artifacts. This book introduces students to the fundamentals of molecular spectroscopy – including UV-visible, infrared, fluorescence, and Raman spectroscopy – in an approachable and comprehensive way. It goes beyond the basics of the subject and provides a detailed look at the interplay between theory and practice, making it ideal for courses in quantitative analysis, instrumental analysis, and biochemistry, as well as courses focused solely on spectroscopy. It is also a valuable resource for practitioners working in laboratories who regularly perform spectroscopic analyses. Spectroscopy: Principles and Instrumentation: Provides extensive coverage of principles, instrumentation, and applications of molecular spectroscopy Facilitates a modular approach to teaching and learning about chemical instrumentation Helps students visualize the effects that electromagnetic radiation in different regions of the spectrum has on matter Connects the fundamental theory of the effects of electromagnetic radiation on matter to the design and use of spectrophotometers Features numerous figures and diagrams to facilitate learning Includes several worked examples and companion exercises throughout each chapter so that readers can check their understanding Offers numerous problems at the end of each chapter to allow readers to apply what they have learned Includes case studies that illustrate how spectroscopy is used in practice, including analyzing works of art, studying the kinetics of enzymatic reactions, detecting explosives, and determining the DNA sequence of the human genome Complements Chromatography: Principles and Instrumentation The book is divided into five chapters that cover the Fundamentals of Spectroscopy, UV-visible Spectroscopy, Fluorescence/Luminescence Spectroscopy, Infrared Spectroscopy, and Raman Spectroscopy. Each chapter details the theory upon which the specific techniques are based, provides ways for readers to visualize the molecular-level effects of electromagnetic radiation on matter, describes the design and components of spectrophotometers, discusses applications of each type of spectroscopy, and includes case studies that illustrate specific applications of spectroscopy. Each chapter is divided into multiple sections using headings and subheadings, making it easy for readers to work through the book and to find specific information relevant to their interests. Numerous figures, exercises, worked examples, and end-of-chapter problems reinforce important concepts and facilitate learning. Spectroscopy: Principles and Instrumentation is an excellent text that prepares undergraduate students and practitioners to operate in modern laboratories.

Provides the tools needed to explore the incredible complexities of the earth's soils Now in its Second Edition, this highly acclaimed text fully equips readers with the skills and knowledge needed to analyze soil and correctly interpret the results. Due to the highly complex nature of soil, the author carefully explains why unusual results are routinely obtained during soil analyses, including the occurrence of methane in soil under oxidative conditions. The text also assists readers in developing their own analytical techniques in order to analyze particular samples or test for particular compounds or properties. The Second Edition of Introduction to Soil Chemistry features four new chapters. Moreover, the entire text has been thoroughly updated and revised. It begins with a review of the history of soil chemistry, introducing fundamental concepts that apply to all soils. Next, the text explores: Basic soil characteristics, horizonation, texture, clay, air, water, solids, organic matter, organisms, and fundamental chemical concepts essential to soil chemistry Tested and proven sampling techniques for soil analysis that provide reliable analytical results Basic soil measurement techniques and extraction procedures Instrumentation to isolate and identify soil chemicals, including plant nutrients and contaminants Detailed examples and figures throughout the text help readers successfully perform soil sampling and analytical methods as well as better understand soil's chemical characteristics. At the end of each chapter, a bibliography and list of references lead to additional resources to explore individual topics in greater depth. Each chapter also offers problem sets, encouraging readers to put their newfound skills into practice. Reflecting the latest research findings and best practices, the Second Edition of Introduction to Soil Chemistry is ideal for both students and soil chemists who want to explore the incredible complexities of the earth's soils.

Discover how to use HILIC to analyze and better understand polar compounds An increasingly popular analytical method, hydrophilic interaction chromatography (HILIC) has the ability to retain and separate polar compounds that are often difficult to analyze by reversed-phase high-performance liquid chromatography (HPLC) or other analytical methods. Offering a comprehensive review, this book enables readers to develop a fundamental understanding of how HILIC works and then apply that knowledge to develop and implement a variety of practical applications. Hydrophilic Interaction Chromatography begins with discussions of HILIC retention mechanisms, stationary phases, and general method development. This sets the foundation for the book's extensive coverage of applications. The authors address unique separation challenges for bioanalytical, environmental, pharmaceutical, and biochemical applications. Moreover, there is a thorough discussion of HILIC in two-dimensional chromatography. With contributions from leading analytical scientists who have extensive experience in HILIC as well as HPLC, Hydrophilic Interaction Chromatography serves as a practical guide for researchers, featuring: Detailed examples of HILIC methods and development approaches Thorough explanations of retention mechanisms and the impact of stationary phase and mobile phase properties on separations Step-by-step guidance for developing efficient, sensitive, and robust HILIC methods References to the primary literature at the end of each chapter Hydrophilic Interaction Chromatography is written for scientists who use or develop analytical methods for the separation of polar compounds. In particular, these researchers will discover how HILIC can be used to analyze and better understand the composition of pharmaceutical, bioanalytical, biochemical, chemical, food, and environmental samples.
