| Credits: | 6 |
| Learning Outcome: | After completing the module, students will be able to evaluate and analyze the fundamental relationships, measurement principles and experimental methods of element analysis. The aim is to provide a basic understanding of the advantages and disadvantages of the various methods for individual problems in applied quantitative element analysis. To this end, students gain a sound understanding of the physical principles of the methods, the most important components and instrumental details of the measuring devices, data analysis and data evaluation as well as sources of error and how to avoid them. They will be able to understand systematic processes for identifying known and unknown substances and the classification of compounds in complex substance systems. At the end of the module, students should be able to apply the acquired knowledge independently and across disciplines to problems of identification and characterization of predominantly inorganic materials. |
