Produktbeschreibung

The validation of analytical methods is based on the characterisation of a measurement procedure (selectivity, sensitivity, repeatability, reproducibility). This volume collects 31 outstanding papers on the topic, mostly published in the period 2000-2003 in the journal "Accreditation and Quality Assurance". They provide the latest understanding, and possibly the rationale why it is important to integrate the concept of validation into the standard procedures of every analytical laboratory. In addition, this anthology considers the benefits to both: the analytical laboratory and the user of the measurement results.

Rezensionen

From the reviews:

"The world at large has become more aware of the importance of analytical measurements and their role in defining what quality is acceptable and what is not! ... overall this is a useful compilation and would serve as a good introduction to and an overview of the field for practicing analytical chemists and scientists particularly from certified laboratories (ISO 17025 etc)." (C. Burgess, Chromatographia, Vol. 62 (3-4), 2005)

"Validation is certainly a hot topic in analytical chemistry since a couple of decades. It is not only an important topic in education of chemical students, but first of all the subject of interest for routine laboratories. ... There is no doubt, that in the field where many analytical chemist consider themselves as experts, such book brings much new and useful information ... . I am sure that this book will be appreciated by many newly educated as well as experienced analysts." (Adam Hulanicki, Chemia Analityczna, Vol. 50, 2005)
