J. Boman’s research at University of Gothenburg (UGOT) lies in the intersection of environmental science, physics and chemistry, with special focus on air and life quality in urban areas in low and middle-income countries. The research is part of the WHO’s assessment of air quality in Kenya. Professor Boman is an evaluator of international research project proposals. In 2015 he chaired the organization of the World Environmental Education Congress in Gothenburg and is now organizing the European Aerosol Conference 2019 in Gothenburg. He headed the Swedish partners in the EU-financed Erasmus+ Knowledge Alliances project “Competencies for A sustainable Socio Economic development” (CASE) (2015-2017) where a new Master’s program was drafted and online sustainability tools were developed. He is coordinating the sustainable development education efforts of the Science faculty at UGOT and if part of the team with similar tasks at the Centre for Sustainable Development (GMV) in Gothenburg. He arranged workshops in Gothenburg (2014) and Nairobi (2015) on Air and Life Quality Development in Nairobi and other Sub-Saharan Africa cities. Funded by SSEESS and Gothenburg Atmospheric Science Centre. In May 2013 he gave a PhD course in Atmospheric science at the Center for Environmental Science, University of Addis Ababa, Ethiopia and is currently a member of the VR-funded collaboration project “Photochemical Smog in China – Formation, transformation, impact and abatement strategies". He has published over 50 peer-reviewed papers in international journals.

Most of the projects are centered on application of the Energy Dispersive X-Ray Fluorescence (EDXRF) analysis technique. This is a nondestructive, multi-elemental technique were elements can be detected down to picogram levels. Applications are mainly dealing with field measurement studies of the air quality in several parts of the world. The research has been financed by Swedish international development agency (Sida) and the research council (VR) for studies in Kenya and Egypt.

The EDXRF technique is also being developed for new applications, to gain better detection levels and to combine the XRF analysis with other analytical techniques.

X-ray flourescence

The objectives are to expand the operational possibilities of the Energy Dispersive X-Ray Fluorescence (EDXRF) spectrometers.

Currently there are two XRF spectrometers available for our research. Both instruments are laboratory built for best possible adoption to the needs of different projects. Both spectrometers are used for multi-elemental, non-destructive analysis of trace elements in the samples.

The EDXRF is based on a three axial geometry in order to reduce the background in the obtained spectra, thus reaching low detection limits. This spectrometer can be used for analysis of almost all kind of samples. The geometry of the spectrometer may be further optimized and vacuum will be used in the future to further lower detection limits.

To reach even lower detection limits and be able to use very minute amounts of sample mass the Total reflection X-Ray Fluorescence (TXRF) spectrometer is used. In this spectrometer the geometry is changed so that the incoming x-rays are totally reflected on a flat sample support surface. This is achieved when the impinging angle is below a certain critical angle. The critical angle is dependent on both the reflector material and the energy of the x-rays. This optimized setup allows detection of elements in the pictogram range. By testing different materials for the reflector/sample holder and special treatments of the reflector surface for different purposes, the analysis can be improved further.

Ideas exist to develop XRF spectrometers for online analysis of small aerosol particles as well as combining the XRF instrumentation with other analytical techniques available and developed in the research group.


I am one of the Directors of studies at the department and I teach on some of our courses. For example:

Aerosols/Aerosoler (KEM720)
Analytical chemistry 1/Analytisk kemi 1 (KEM070)
Energy and environment/Energi och miljö (ES2417)
Environmental chemistry/Miljökemi (KEM490)

For more information on these courses please refer to the platform GUL.
