General course information
The goal of the course is to give understanding about basic concepts used in chemical metrology and, first of all, understanding how the uncertainty of the measurements can be evaluated and optimized to fit for the purpose of the investigation. Analytical measurements rely on samples. If the samples are not representative the effort made to analyze them is time wasted and conclusions drawn may be fatally wrong. The major topic of this course is, therefore, sampling. Understanding is solidified with computer exercises (optionally with your own data).
Topics of lectures
The introduction of the course covers basic terminology of chemical metrology and in quality control of chemical measurements. Large part of the course is devoted to sampling for chemical analysis covering the basic theory of sampling (TOS), uncertainty estimation and optimization of the measurement chain.
Course reading
The course readings consist of selected lecture notes and PowerPoint slides. Additionally, scientific papers on the applications are distributed.
