Method Validation and Uncertainity of Measurement
Method validation is the process that provides evidence that a given analytical method, when correctly applied, produces results that are fit for purpose. No matter how well a method performs elsewhere, analysts need to confirm that the method is valid when applied in their laboratory. There is now much greater emphasis on method validation in the ISO/IEC 17025 accreditation standard. During the course there is ample opportunity to practice the principles learned through lap-top based workshops using Excel.
Uncertainty of Measurement
Any laboratory wishing to achieve accreditation to ISO/IEC 17025:2005 is required to have, and to apply, policies and procedures for the estimation, use and reporting of uncertainties of measurement for any tests or calibrations covered by their scope of accreditation.
What are the benefits?
- This course will help participants understand method validation and its requirements; select and apply the statistics required during method validation; select and use the appropriate types of method validation studies and appreciate and understand the links with measurement uncertainty.
- Drawing on experience of training skills of estimating uncertainty of measurement to more than two thousand testing and calibration practitioners over the years, this course aims to provide participants with an appreciation of the concept of uncertainty of measurement in both a testing and calibration environment, and uses a combination of lectures and interactive exercises and demonstrations to take participants through the process of calculating uncertainties.
The course will cover:
- Introduction to statistics for method validation
- Significance testing – t-tests and the F- test Analysis of variance (ANOVA) Linear regression
- Introduction to the concepts of method validation
