Measurement uncertainty evaluation based on in-house validation data (online)
Overview
Eurachem, in cooperation with CITAC, invited members of the international analytical community to attend this free online workshop on the topic of measurement uncertainty evaluation using method validation data.
This workshop presented the principles of a new Eurachem Guide which is to complement the existing guide, Quantifying Uncertainty in Analytical Measurement, by providing a simplified evaluation of the uncertainty of measurements in routine chemistry based on recovery and precision studies performed during in-house validation.
The workshop was attended by over 600 participants* over the two days.
* Based on distinct participant count
