He is an assistant Professor 7 of the Department of Chemistry, UP Visayas, Graduate of BS Chemistry from University of the Philippines, Visayas ,European Masters in Quality in Analytical Laboratories from the University of Barcelona, Spain and the University of Bergen, Norway and Masters in Chemistry from the University of the Philippines, Visayas.

Description

The accuracy of a measurement result is depicted by measurement uncertainty. It can be conducted through measuring instrument and from other sources (e.g. operator, environment).

The new two-day training course is designed to give participants the relevant skills and knowledge to apply measurement uncertainty as a requirement of ISO 17025:2017 to laboratory processes. It takes a practical approach to measurement uncertainty, where learners will be able to comprehend its importance, causes, mitigation techniques and overall application to test methods in order to report test results with correct uncertainty values.

Objectives

Upon completion of this course, learners will be able to:

• Understand the basics and the importance of measurement uncertainty;
• Familiarize themselves with ISO 17025 and the requirements for MU in ISO 17025:2017;
• Identify the sources that cause measurement uncertainty and how to quantify them; and
• Learn how to estimate Measurement Uncertainty in laboratory analyses.

Learners will need to demonstrate acceptable performance in these areas, through workshops, in order to successfully complete the training. This training will soon be accredited by the Professional Regulation Commission (PRC) for CPD units.
