Aim:

Measurement uncertainty and traceability of measurement results are essential for the evaluation of measurement results.

Reference materials are key tools for achieving traceability of measurements, proving accuracy of methods and demonstrating proficiency of laboratories.

This course provides participants with the theoretical basis for the estimation of measurement uncertainty and establishment of traceability. This knowledge is applied to the proper selection and use of reference materials.

Who should attend?

Laboratory managers and practitioners in analytical laboratories who use reference materials for statistical quality control, method validation and calibration and need to assess measurement uncertainties on customer’s demand or as requirement of ISO 17025.

ISO 17025 auditors who need to assess the estimation of measurement uncertainties and the correct application of certified reference materials.

Topics tackled:

Uncertainty estimation
- What are the basic principles?
- How to estimate uncertainty from validation data?
- How can I use reference materials to estimate my measurement uncertainty?

Establishing traceability
- What do I have to do to make my results traceable?
- How can I establish traceability with reference materials?

Reference material selection
- Where can I find reference materials?
- Which material is the right one for me?

Reference material handling
- How much of each material must I use?
- How should I store my materials?
- How do I correct for moisture?

Reference materials use
- How can I demonstrate trueness?
- How can I demonstrate my method proficiency?

Making full use of available information
- What do the terms on a certificate mean?
- What can I do with a certification report?
