This book deals exclusively and comprehensively with the role of proficiency testing in the quality assurance of analytical data. It covers in detail proficiency testing schemes from the perspectives of scheme organisers, participant laboratories and the ultimate end-users of analytical data. A wide variety of topics are addressed including the organisation, effectiveness, applicability, and the costs and benefits of proficiency testing. Procedures for the evaluation and interpretation of laboratory proficiency, and the relation of proficiency testing to other quality assurance measures are also discussed. Proficiency Testing in Analytical Chemistry is an important addition to the literature on proficiency testing and is essential reading for practising analytical chemists and all organisations and individuals with an interest in the quality of analytical data.

Reference materials play an important role in analytical chemistry, where they are used by analysts for a variety of purposes, including: checking and calibrating instruments; validating methods and estimating the uncertainty of analytical measurements; checking laboratory and analyst performance; and internal quality control. This book provides guidance and information for the users of certified reference materials (CRMs), explaining how they can best be used to achieve valid analytical measurements and improve quality in the analytical laboratory. General information on CRMs and how they are produced sets the scene for readers. The statistics relating to CRM use are then explained in an easy-to-understand manner, and this is followed by sections covering the main uses of CRMs. Detailed worked examples are used throughout. Structured and comprehensive in coverage, this book will be welcomed by all users of certified reference materials.

Where do Scottish literatures, art, and cinema stand today? What and how do Scottish Studies investigate? Creative writers and scholars give answers to these questions and address vital concerns in Scottish, British, and European history from the Union debate and the Enlightenment to Brexit, ethnic questions, and Scottish film. They present new insights on James Macpherson, Robert Burns, John Galt, J. M. Barrie, Walter Scott, James Robertson, war poetry, new Scottish writing, and nature writing. The contributions highlight old and new networking and media as well as the persistent influences of the past on the present, analyzing a wide range of texts, media and art forms with approaches from literary, cultural, media, theatre, history, political, and philosophical studies.
