Guide to Quality in Analytical Chemistry - 4th edition (2026)

Content

QAC 2016 cover 180hThe aim of this guide is to provide laboratories with guidance on best practice for the analytical operations they carry out. The guidance covers both qualitative and quantitative analysis carried out on a routine or non-routine basis.

This 4th edition is a revision of the CITAC/Eurachem Guide published in 2016. This revision reflects changes that were introduced with the publication of the 2017 version of ISO/IEC 17025.

The Guide focuses on the requirements of ISO/IEC 17025, however the content should also be of use to organisations seeking accreditation or certification against the requirements of standards such as ISO 15189 or ISO 9001, or compliance with the Principles of Good Laboratory Practice. The Guide will also provide useful information both for laboratories that wish to establish a quality management system but are not seeking formal recognition, and for those involved in education and training.
