Introduction

Quantitative chemical measurement has a degree of uncertainty linked to its results which is determined by the performance characteristics of the analytical method used. Measurement uncertainty has often been evaluated on the basis of repeatability and reproducibility of data, but the measurement uncertainty, as expressed in the “Guide to the Expression of Uncertainty in Measurement” published by ISO in 1993, goes further and gives general rules for the evaluation of measurement uncertainty based on both statistical (Type A) and non-statistical (Type B) uncertainties. The course covers the bulk of the methods and techniques documented in the ISO guide and give a general principle to the calculation of measurement uncertainty in quantitative chemical analyses.

Objectives

Upon the successful completion of this course, the participants will have an understanding of:

  • Concepts involved in the calculation of measurement uncertainty.
  • Calculating measurement uncertainty in a practical and pragmatic manner.
  • Defining measurement processes.
  • Identifying sources of measurement error.
  • Selecting appropriate error distributions.
  • Using different methods to evaluate measurement uncertainty.
  • Measurement uncertainty by practice methods.

Who Should Attend?

The course is designed for chemists, lab technicians, chemical engineers, instrument engineers and lab supervisors/managers.
