Sample Preparation (4 ECTS)

Objective

The course includes an introduction to the most common sample preparation techniques used in chromatographic and metal analyses – their theoretical background and applications. The student will learn how to select an appropriate sample preparation technique for different kinds of analyses. In addition, he/she will be able to assess the significance of sample preparation for the analytical result.
