As independent researcher of "Onderzoek & Beleving" Hans publishes scientific research in peer reviewed scientific journals. The subject of these  papers is within his speciality, being the isotope geochemistry of chlorine and/or bromine isotopes or the hydrogeochemistry of ground- and mineral waters.

The following papers  have been published under the imprint of

"Onderzoek & Beleving":

Experimental determination of stable chlorine and bromine isotope fractionation during precipitation of salt from a saturated solution.

Chemical Geology 433:46-56. HGM Eggenkamp, M Bonifaci, M Ader, P Agrinier (2016)

Chlorine isotope and Cl-Br fractionation in fluids of Poás volcano (Costa  Rica): Insight into an active volcanic-hydrothermal system.

Journal of Volcanology and Geothermal Research  325:70-85. A Rodríquez, HGM Eggenkamp, M Martínez-Cruz, MJ van Bergen (2016)

Why are variations in bromine isotope compositions in the Earth's history larger than chlorine isotope compositions?

Annales UMCS, Sectio AAA 70:185-196.  HGM Eggenkamp (2015)

Comment on ‘‘Stable isotope fractionation of chlorine during the precipitation of single chloride minerals’’ by Luo, C.-g., Xiao, Y.-k., Wen, H.-j., Ma, H.-z., Ma, Y.-q., Zhang, Y.-l., Zhang, Y.-x. and He, M.-y. [Applied Geochemistry 47 (2014) 141–149].

Applied Geochemistry  54:111-116. doi:10.1016/j.apgeochem.2014.11.018    HGM Eggenkamp (2015)


Hans received a grant under the

European Union's Horizon 2020 Research and Innovation Programme under the Marie Sklodowska-Curie Actions (grant agreement No. 702001, Brisoactions)

This project has been succesfully ended and Hans found a new project in Tübingen, Germany.

There he studies the geochemical behaviour of halogens and their stable isotopes in peralkaline intrusions with a team of petrologists. The first time he is profesionally engaged in the study of rocks instead of water.
