The issue of quality assurance in the analytical chemistry laboratory has become of great importance in recent years.
Quality Assurance in Analytical Chemistry introduces the reader to the whole concept of quality assurance. It discusses how all aspects of chemical analysis, from sampling and method selection to choice of equipment and the taking and reporting of measurements affect the quality of analytical data. Finally, the implementation and use of quality systems are covered.

Quality Assurance in Analytical Chemistry
Chapter One
The Need for Reliable Results
Learning Objectives
To understand why analytical measurements need to be made.
To understand the importance of producing reliable results.
To be able to define what is meant by 'quality'.
1.1 Why Analytical Work is Required
Measurements affect the daily lives of every citizen. Sound, accurate and reliable measurements, be they physical, chemical or biological, are essential to the functioning of modern society. For these reasons, advanced nations spend up to 6% of their Gross National Product (GNP) on measurements and measurement-related operations.
Informed debate and decisions on such important matters as the depletion of the ozone layer, acid rain and the quality of waterways all depend on the data provided by analytical chemists. Forensic evidence also often depends on chemical measurements. National and international trade are critically dependent on analytical results. Chemical composition is often the basis for the definition of the nature of goods and tariff classification. In all of these areas not only is it important to get the right answer but it is essential that the user of the results is confident and assured that the data are truly representative of the sample and that the results are defendable, traceable and mutually acceptable by all laboratories.
The role of the analytical chemist has not changed since the time analysts discovered that naturally occurring products were composite materials. For example, when it was discovered that carrots helped prevent 'night blindness' it was an analytical chemist who separated out the variou
