RECX Oslo Instrument Scientists

The specialist scientists at the Oslo RECX lab can help you with your experiments and serve as contacts for instrument problems etc.:

David Wragg (Overall lab manager, powder and single crystal diffraction specialist)

Reidar Lund (Small angle scattering specialist)

Sigurd Øien (Single crystal XRD specialist)

Øystein Fjellvåg (Thin film studies specialist)

Vegar Øygarden (Powder diffraction specialist)



The Oslo RECX lab will feature in the TV program “TV2 Hjelper Deg”. Along with prof Carl Henrik Gørbitz we helped to analyse two brands of dishwasher detergent using powder XRD for phase identification and quantitative analysis.
