The Fitness for Purpose of Analytical Methods

The third edition of Eurachem’s flagship guide provides updated, practical guidance on method validation, verification, sampling, and fitness for purpose, aligned with ISO/IEC 17025:2017.

<h3><strong>The Fitness for Purpose of Analytical Methods: A Laboratory Guide to Method Validation and Related Topics: Third edition (2025)</strong></h3><p><strong>Author: </strong>H. Cantwell</p><p>This guide was first issued in 1998 and the second edition published in 2014. Over the years it has been one of the most popular of the Eurachem guides. Since the release of the first edition, however, there have been many changes in terminology, working practices, reference documents and requirements. This third edition, produced by the Eurachem Method Validation Working Group, forms a thorough revision of the 2014 edition.</p><p>This third edition includes a section on sampling and sample handling as <strong>ISO/IEC 17025:2017</strong> introduced a focus on sampling associated with the testing or calibration being carried out by the laboratory and further guidance on assessing the calibration function has been included. The Guide is also now supported by a number of supplementary guidance documents – please see the section on supplementary guidance below.</p><h4><strong>Contents</strong></h4><p>This third edition includes guidance on:</p><ul><li>The importance of fitness for purpose;</li><li>The concept of method validation and verification;</li><li>How a method validation or verification study should be performed and how much should be done;</li><li>Sampling and sample handling in relation to method validation;</li><li>A thorough explanation of the various validation parameters (performance characteristics) and related topics;</li><li>Follow-up on the validation study (reporting, use of performance data in Internal Quality Control);</li><li>Documentation of analytical methods.</li></ul><p>Annexes also describe the statistical basis of detection limits and analysis of variance for precision studies, and add a check list to aid users in selecting and determining the validity of a test kit.</p><p>In preparing this guidance, the Working Group has aimed at the right balance between giving a solid theoretical background for method validation studies and providing practical guidelines on how to plan, perform and evaluate such studies in the laboratories.</p><p>The approach is generic in the sense that the Guide does not focus on particular fields of application (food, environment, pharmaceuticals etc.). However, the guide includes references to a number of specific guides in fields where different practices have been developed and become common.</p><p>The guide also includes a full bibliography. Further literature references on method validation can be found in the section "Validation of analytical methods" in the Reading list on this website.</p>

Terminology in Analytical Measurement: Introduction to VIM 3

This Eurachem guide introduces VIM 3 terminology relevant to analytical laboratories, explaining key metrological concepts for chemical, biological, and clinical measurements with practical examples.

<h3><strong>Terminology in Analytical Measurement: Introduction to VIM 3 (Second Edition 2023)</strong></h3><p><strong>Author: </strong>V. J. Barwick (Ed.)</p><h4><strong>Contents</strong></h4><p>This guide has been produced by members of the Eurachem Education and Training Working Group and others co-opted to the Project group for this task.</p><p>In the world of metrology – the science of measurement and its application – there is a language which has to be learned. The International Vocabulary of Metrology (VIM) was produced to provide a common language, primarily for physical measurements. The VIM 3 is a consistent set of concepts each described by a unique term, the ‘label’ of the concept. VIM 3 is applicable across all scientific disciplines thus making it relevant to those involved in performing measurements in chemistry and biology. Consistent definitions of concepts with their associated terms and symbols are essential if analysts and customers across the globe are to understand each other.</p><p>This Eurachem Guide discusses a selection of the concepts in VIM 3, focusing on those most likely to be encountered in analytical laboratories. It aims to cover chemical, biological and clinical measurements and gives examples over and above those in the notes accompanying the definitions in VIM 3. The guide is intended for laboratory staff, accreditation bodies, for those commissioning measurements and for those using measurement results. Lecturers and trainers may also find this guide useful when teaching aspects of metrology.</p><p>In this second edition the scope and structure, and the terms and concepts discussed, remain unchanged from the first edition. However, all sections have been reviewed and, where necessary, the text has been revised to improve clarity and ensure consistency with current international guidance at the time of publication.</p>
