Evaluating measurement uncertainty will be one of the most challenging tasks for many laboratories in the field of analytical chemistry for the next few years. The CITAC/ Eurachem working group supports these activities through this site and with the recently published guide "Quantifying Uncertainty in Analytical Measurement" (second edition May 2000). If you would like to have a hard-copy of this guide you can either download the .pdf-file or order a copy from the Eurachem secretary (BAM, Berlin). You will find the following content on this site: Guide: A full html-version of the guide. The full text can be searched using an excite search engine. Examples: You may submit your uncertainty evaluations and seek comments on them in the forum. These examples will be posted here, but there will be no guarantee that they fully comply with the content of the guide. Glossary: Definition of terms we need to understand each other. Forum: Here you can ask questions, ask for advice and comment on
