Evaluation of Measurement Uncertainty in Titration

In order to use the result of a chemical analysis for other purposes, its quality must be assessed. One important quality feature is the probability that the result coincides with the ‘true’ value. It is obtained by the evaluation of the measurement uncertainty. The webinar ‘Evaluation of Measurement Uncertainty in Titration’ guides you through the individual steps of this evaluation by using the comprehensive example of the titrimetric content determination of sodium hydroxide with potassium hydrogen phthalate. The shown principle can be applied to any other titrimetric analysis.

What is measurement uncertainty?

Measurement uncertainty describes the range within the values of a measurement, i.e. titration, can reasonably be attributed.

What is measurement uncertainty needed for?

It enables us to assess the reliability of a measurement, i.e. titration

Why does a lab need to know the measurement uncertainty?

Test- and calibration laboratories working in the following areas, which are accredited according to ISO/IEC/EC/DIN 17025 (2005), have to know how to evaluate the measurement uncertainty:

  • Food and beverages
  • Pharmaceutical
  • Medical-analytical laboratories
  • Forensic chemistry
  • Doping control etc.

This webinar covers the following topics:

  • Background of measurement uncertainty
  • The four steps of evaluation of measurement uncertainty
