In the analytical process, the sample preparation includes the work steps between sampling and measurement, whereby the original samples are to be converted into a measurable state. The lecture is intended to cover the area of organic analytics, in which there is generally an enrichment or concentration of any analytes and a separation of the analytes from the interfering matrix. The step of sample preparation, after sampling, is often the step with the greatest error-proneness. In many cases it is also the most labor-intensive. Therefore, the aim nowadays is to automate sample preparation to a large extent. The lecture is intended to give an overview of the existing classic and modern solvent-free techniques. A focus will be on the physico-chemical parameters that lie behind these methods. As soon as possible, methods available at the chair are explained for better practical relevance in addition to the devices in the laboratory and shown through handouts in the lecture.
The lecture takes place in the main course in the winter semester and comprises 2 SWS.
