In this book on Fundamentals of Mass Determination, the definition and dissemination of units of mass is explained, starting with an introduction to metrology and mass determination. Establishing a mass scale requires corresponding mass standards and mass comparators. The metrological requirements for weighing instruments, weight pieces, and measuring conditions are explained and discussed based on international directives and applicable legal regulations. International directives and institutions are striving towards the worldwide uniform implementation of these requirements. Processes used to determine density and volume are described to the extent that they apply to mass determination. Calculating measurement uncertainty entails taking into consideration the effect of influence variables on mass determination. An overview of this topic is provided to make it easier to determine and specify measurement uncertainty in practice, while additional information in the form of tables, illustrations, and literature references allow the reader to study mass metrology further.

"Measurement of mass is one of the most frequently carried out operations in an analytical laboratory. Accurate mass measurements are required for such purposes as: obtaining a known quantity of a sample for analysis ; preparation of analytical reagents ; and preparation of calibration standards. This document provides guidance on various important aspects of mass measurement as it is commonly carried out in alalytical laboratories." - page 1.

"How much does it weigh?" seems a simple question. To scientists and engineers, however, the answer is far from simple, and determining the answer demands consideration of an almost overwhelming number of factors. With an intriguing blend of history, fundamentals, and technical details, the Handbook of Mass Measurement sets forth the details

This second edition of Mass Metrology: The Newly Defined Kilogram has been thoroughly revised to reflect the recent redefinition of the kilogram in terms of Planck’s constant. The necessity of defining the kilogram in terms of physical constants was already underscored in the first edition. However, the kilogram can also be defined in terms of Avogadro’s number, using a collection of ions of heavy elements, by the levitation method, or using voltage and watt balances. The book also addresses the concepts of gravitational, inertial and conventional mass, and describes in detail the variation of acceleration due to gravity. Further topics covered in this second edition include: the effect of gravity variations on the reading of electronic balances derived with respect to latitude, altitude and earth topography; the classification of weights by the OIML; and maximum permissible error in different categories of weights prescribed by national and international organizations. The book also discusses group weighing techniques and the use of nanotechnology for the detection of mass differences as small as 10-24 g. Last but not least, readers will find details on the XRCD method for defining the kilogram in terms of Planck’s constant.

The isotope dilution mass spectrometry (IDMS) technique is well known and widely reported in the literature. However, its application can present considerable difficulties with regard to obtaining reliable results. Produced jointly by the Royal Society of Chemistry's Analytical Methods Committee and the Valid Analytical Measurement (VAM) programme, the aim of this book is to provide a simplified yet robust methodology, together with adequate guidance, to enable laboratories wishing to use the technique to obtain reliable data. The methodologies, for inorganic and organic mass spectrometry, which use exact and approximate matching, are illustrated with worked examples and clear diagrammatic representations. A comprehensive glossary of terms, references to key publications and an extensive IDMS bibliography are also provided. Clear and comprehensive in coverage, Guidelines for Achieving High Accuracy in Isotope Dilution Mass Spectrometry (IDMS) will provide valuable assistance to a wide variety of analytical chemists interested in applying the IDMS technique to their own measurement applications.

This book describes the significance of metrology for inclusive growth in India and explains its application in the areas of physical–mechanical engineering, electrical and electronics, Indian standard time measurements, electromagnetic radiation, environment, biomedical, materials and Bhartiya Nirdeshak Dravyas (BND®). Using the framework of “Aswal Model”, it connects the metrology, in association with accreditation and standards, to the areas of science and technology, government and regulatory agencies, civil society and media, and various other industries. It presents critical analyses of the contributions made by CSIR-National Physical Laboratory (CSIR-NPL), India, through its world-class science and apex measurement facilities of international equivalence in the areas of industrial growth, strategic sector growth, environmental protection, cybersecurity, sustainable energy, affordable health, international trade, policy-making, etc. The book will be useful for science and engineering students, researchers, policymakers and entrepreneurs.
