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.

What has happened to American liberty? One of the major hindrances to the advancement of mankind is the subliminal mind control of political correctness - or PC. Once thought of as merely a method by which society could become more sensitive to the needs of others, PC has become a brainwashing technique used by those who wish to control not only our minds, but also our actions. Those who use PC in this manner prey on natural human compassions to further their own hidden agendas. They will advance their agendas by almost any means necessary, including the use of false accusations and outright lies. Far too often those agendas have very little, if anything, to do with the problems they claim to solve. In most cases, they ultimately harm the very people they claim to help.

Without Firing a Shot is not about trading one form of mind control for another. Using real-life examples and in-depth analysis, the author explains how to look for the signs of the shell game known as political correctness in order to better understand the world in which we live. Whether you agree with his opinions or not doesn't really matter. His thought-provoking commentary challenges and encourages you to discover a method by which you can free yourself from preconceived political ideologies, research the facts with an open mind, discover the truth, and draw your own conclusions.
