Book Synopsis Units of Measurement by : S. V. Gupta
Download or read book Units of Measurement written by S. V. Gupta and published by Springer Nature. This book was released on 2020-06-23 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers a comprehensive overview of units of measurement. Beginning with a historical look at metrology in Ancient India, the book explains fundamental concepts in metrology such as basic, derived and dimensionless quantities, and introduces the concept of quantity calculus. It discusses and critically examines various three and four-dimensional systems of units used both presently and in the past, while explaining why only four base units are needed for a system of measurement. It discusses the Metre Convention as well as the creation of the International Bureau of Weights and Measures, and gives a detailed look at the evolution of the current SI base units of time, length, mass, electric current, temperature, intensity of illumination and substance. This updated second edition is extended with timely new chapters discussing past efforts to redefine the SI base units as well as the most recent 2019 redefinitions based entirely on the speed of light and other fundamental physical constants. Additionally, it provides biographical presentations of many of the historical figures behind commonly used units of measurements, such as Newton, Joule and Ohm, With its accessible and comprehensive treatment of the field, together with its unique presentation of the underlying history, this book is well suited to any student and researcher interested in the practical and historical aspects of the field of metrology.

Book Synopsis Calibration in Analytical Science by : Paweł Kościelniak
Download or read book Calibration in Analytical Science written by Paweł Kościelniak and published by John Wiley & Sons. This book was released on 2023-02-13 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calibration in Analytical Science Designed to help analytical chemists save time and money by selecting the best calibration method in a quality control, substance monitoring, or research setting Univariate analytical calibration is a vital step in every chemical procedure that involves determining the identity or concentration of a particular substance. Depending on the type of instrument and measurement, analytical chemists need to follow different calibration strategies and protocols to ensure their instruments yield accurate readings. Calibration in Analytical Science systematically classifies and describes a wide range of calibration methods and procedures based on mathematical and empirical models for use in qualitative and quantitative analysis. Focusing on the chemical aspects of analytical calibration, this much-needed reference uses a set of equipment-independent terms and definitions that are easily transferable to the calibration strategies of any analytical process. The theoretical basis for calibration of each analytical mode is described and applied to common analytical tasks of increasing levels of difficulty and complexity. Throughout the book, the author illustrates how to combine different calibration approaches to create new calibration strategies with extended capabilities. Describes different calibration methods and procedures for determining the nature and quantity of sample components in different ways Classifies various calibration methods in both qualitative and quantitative analysis Demonstrates how the random and systematic errors of an analytical method can be minimized by the proper calibration strategy Discusses current theoretical and methodological questions in calibration research Highlights how calibration approaches can diagnose, evaluate, and eliminate analytical errors Includes a concluding chapter on the contribution of calibration to the greening of analytical chemistry Calibration in Analytical Science: Methods and Procedures is a must-have reference for analytical chemists working in academia and industry, chemists of various specialties involved in chemical analysis, and advanced undergraduate and graduate students taking courses in advanced analytical chemistry.

Book Synopsis NMR Spectroscopy in Pharmaceutical Analysis by : Iwona Wawer
Download or read book NMR Spectroscopy in Pharmaceutical Analysis written by Iwona Wawer and published by Elsevier. This book was released on 2017-07-07 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: For almost a decade, quantitative NMR spectroscopy (qNMR) has been established as valuable tool in drug analysis. In all disciplines, i. e. drug identification, impurity profiling and assay, qNMR can be utilized. Separation techniques such as high performance liquid chromatography, gas chromatography, super fluid chromatography and capillary electrophoresis techniques, govern the purity evaluation of drugs. However, these techniques are not always able to solve the analytical problems often resulting in insufficient methods. Nevertheless such methods find their way into international pharmacopoeias. Thus, the aim of the book is to describe the possibilities of qNMR in pharmaceutical analysis. Beside the introduction to the physical fundamentals and techniques the principles of the application in drug analysis are described: quality evaluation of drugs, polymer characterization, natural products and corresponding reference compounds, metabolism, and solid phase NMR spectroscopy for the characterization drug substances, e.g. the water content, polymorphism, and drug formulations, e.g. tablets, powders. This part is accompanied by more special chapters dealing with representative examples. They give more detailed information by means of concrete examples. Combines theory, techniques, and concrete applications—all of which closely resemble the laboratory experience Considers international pharmacopoeias, addressing the concern for licensing Features the work of academics and researchers, appealing to a broad readership
Book Synopsis Measurement Uncertainty in Chemical Analysis by : Paul De Bièvre
Download or read book Measurement Uncertainty in Chemical Analysis written by Paul De Bièvre and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now becoming recognized in the measurement community that it is as important to communicate the uncertainty related to a specific measurement as it is to report the measurement itself. Without knowing the uncertainty, it is impossible for the users of the result to know what confidence can be placed in it; it is also impossible to assess the comparability of different measurements of the same parameter. This volume collects 20 outstanding papers on the topic, mostly published from 1999-2002 in the journal "Accreditation and Quality Assurance." They provide the rationale for why it is important to evaluate and report the uncertainty of a result in a consistent manner. They also describe the concept of uncertainty, the methodology for evaluating uncertainty, and the advantages of using suitable reference materials. Finally, the benefits to both the analytical laboratory and the user of the results are considered.
