A Practical Guide to Total Reflection X-ray Fluorescence discusses how a wide range of samples can be analyzed using Total Reflection X-ray Fluorescence (TXRF) to obtain meaningful and accurate results. Sample handling is a complex problem and often very targeted approaches are needed. The strengths and weaknesses of the method are discussed in the context of each application in this book. This includes guidelines and suggestions of how to treat and analyze different samples and how to evaluate the data. In addition to sample handling, users of TXRF will learn how to use and calibrate the instrumentation, what specific features are present and which experimental parameters need to be considered, and how to evaluate the data.The book is divided into two parts. with the first part describing the theoretical aspects of the method and the second part being solely dedicated to its applications. The book emphasizes a practical approach to the method, including advantages and also limitations. The primary concept throughout the book is the chemical measurement process and how it applies to TXRF analysis. The concept is introduced in the first part of the book describing its main aspects like samples, sample handling, and quantification. In the second part of the book the topic is applied to the different application fields of TXRF, presented as separated chapters. Key case studies emphasizing the strength of the method are included in each of the chapters. The book also explains in detail the calibration of the instrument and method, experimental parameters to apply, quantification procedures, and spectra evaluation.This book serves as a valuable resource for users and users-to-be in the field of elemental and trace analysis. All co-authors offer extensive experience in the field of TXRF and can guide users through the chemical measurement process of a specific field of application including what elements are most suitable, and what issues may occur.

The first hands-on guide to XRD and XRF sampling and specimen preparation Systematic errors from poor sampling and improper specimen preparation can easily render X-ray diffraction (XRD) and X-ray fluorescence (XRF) data of questionable use for analysis. But, until now, the practical information that can help to reduce these errors has never been readily available in one volume. This book fills a vital gap in the literature, bringing together a wealth of material previously available only in workbooks, company manuals, and other inside sources. It provides detailed coverage of the major tasks involved in X-ray analysis - complete with theory, step-by-step methods, equipment suggestions, and problem-solving tips. With a full complement of tools and techniques, this comprehensive guide helps both beginners and experienced analysts to make the best decision on sample treatment and get accurate XRD and XRF results-saving valuable time, money, and effort. Covers X-ray techniques for analyzing biological, geological, metallic, ceramic, and other materials * Addresses all aspects of specimen preparation, including handling unusual or very small samples, liquids and solutions, and more * Features special chapters on specimen preparation equipment and XRF standards * Contains useful bibliography and helpful references.
