Every analytical measurement has some uncertainty associated with it due to unavoidable errors in the measurement process. Knowledge of this uncertainty allows the reliability of the results to be assessed to determine if they are ‘fit for purpose’.  Estimating measurement of uncertainty is a complex task.

The course provides all the information, knowledge and skills needed to estimate uncertainty for analytical methods, step-by-step, from start to finish.  It is excellent preparation for those who need to estimate the uncertainty of analytical methods for ISO/IEC 17025 accreditation.

This course is highly recommended for Quality Managers, Technical Managers, Chemists and quality control staff. It is specifically targeted for those dealing with the regulatory testing of precious/non-precious jewellery and consumer products and using equipment such as ICP-OES/ AAS/XRF/Fire Assay/ titrations and similar analytical instruments.

On completion of this course, delegates will be able to estimate uncertainty for laboratory methods and confidently answer any questions concerning uncertainty estimates.



Refreshments are available throughout the day; a sandwich lunch is included in the course price.


The course covers the introductory concepts of uncertainty to the completion of an uncertainty budget including.

  1. A non-mathematical approach to the statistical calculation and its use in estimating uncertainty.
  2. Identifying and quantifying each source of uncertainty, including rules for uncertainty calculations.
  3. Cause and effect diagram.
  4. Using data from method validation studies to estimate uncertainty.
  5. Completing the uncertainty budget for various content & released based methods in workshops using excel spreadsheets.

Course material in the form of powerpoint presentation and a USB drive with all questions and answers of respective exercises completed during various practical’s/workshops conducted during the course.
