Validation of Measurement Procedures that Include Sampling (VaMPIS) – a new Eurachem Guide

Michael Ramsey

Abstract

The validation of measurement procedures has traditionally focused on the analytical procedures applied to extracted samples within the laboratory (i.e. ex situ). However, it has been widely accepted that the measurement procedure actually begins at the moment that a sample is taken from the sampling target. The validation process therefore needs to be expanded to include the primary sampling procedure, and how to do this is explained in the new Eurachem Guide on Validation of Measurement Procedures that Include Sampling (VaMPIS). It is applicable to measurement procedures whether they are applied ex situ, or in situ when no physical sample is extracted. It can also be applied either simultaneously to the whole measurement procedure, or sequentially when a previously validated analytical procedure is used. Worked examples are given in this new Guide for each of these situations.
