PARAllel FACtor analysis (PARAFAC) is used to interpret natural organic matter (NOM) fluorescence when measured using excitation emission matrix (EEM) spectroscopy. PARAFAC resolves overlapping fluorescence signals into independent spectra representing different chemical components. When fluorescence signals conform to Beers Law, this process can lead to the identification and quantification of independently varying fluorophores. However, many practical and analytical hurdles stand between EEM datasets and their chemical interpretation. This course will provide instruction on best-practice application of PARAFAC to fluorescence datasets using the drEEM toolbox for MATLAB.
This course is offered through the PhD program in Water Environment Technology at the Department of Architecture and Civil Engineering, Chalmers University of Technology. Participants who complete the course including submitting three assignments can obtain official credit (5 ETS points, Pass/Fail grade).Topics to be covered
- Flourescence and PARAFAC theory
