Estimation of Measurement Uncertainty in Labs: a requirement for ISO 17025 Accreditation

Knowledge of the uncertainty of measurement of testing and calibration results is fundamentally important for laboratories, their clients and all institutions using these results for comparative purposes. Uncertainty of measurement is a very important metric of the quality of a result or a testing method.
Main points covered:
• To introduce the basic concepts related to measurement results and measurement uncertainty
• Explain the relevance of these concepts to chemical analysis data
• Introduce mathematical concepts, uncertainty sources and important approaches for estimation of measurement uncertainty
Presenter:
This webinar was presented by Dotun Bolade, who is an Analytical Chemist/Environmental Scientist by training and practice with years of experience in laboratory instrumentation and automation. For him, ISO management systems have become second nature having worked in environments where ISO 9001, 14001, 18001 and 17025 have been fully implemented. He is a Certified PECB ISO/IEC 17025 Lead Assessor.
