Bioanalytical methodologies with emphasis on use of chromatography and mass spectrometry in metabolomics analysis

The goal of the course is to enable the students to understand more of the theoretical and practical aspects of various combinations of chromatography and mass spectrometry commonly used in metabolomics analysis. It is addressed to students at master- and PhD level who work with chromatography (GC and LC) and mass spectrometry. It is also of interest to those who are using service and obtaining results from metabolomics and proteomics platforms. Registration deadline: 31 January 2019. ​
