Validation of Measurement Procedures that Include Sampling (1st Ed)

A supplement to:
“The Fitness for Purpose of Analytical Methods”
“Measurement Uncertainty arising from Sampling”

Vampis converge txt outGuidance is given on how to validate a measuring procedure that includes the primary sampling (VaMPIS). It is a supplement to existing Eurachem guidance on “The Fitness for Purpose of Analytical Methods” and “Measurement Uncertainty arising from Sampling”. The overall aim is to extend the concept of ‘validation of a measurement procedure’ beyond the validation of the analytical method (or procedure) alone, in order to include the primary sampling (and physical sample preparation) within the validation process.

Ideally, VaMPIS can be applied to validate the whole measurement procedure simultaneously. Alternatively, VaMPIS can be applied sequentially by using an analytical procedure that has already been validated for this purpose in isolation, but then extending it to include the sampling step.

The key characteristic that enables validation of both the sampling and the analytical procedures is the measurement uncertainty, when supported by the performance characteristics that apply to the analytical procedure, which are already described in the Fitness for Purpose guide.

Two worked examples are provided to demonstrate how VaMPIS can be applied to both ex situ analysis in a laboratory of an extracted sample, and also to in situ analysis made ‘in the field’, without extracting a physical sample. Guidance is also given on the management and QC issues that are needed in order to integrate the sampling and the analytical steps, which have previously usually not had a unified and coordinated approach to data quality.
