Dr Geoffrey Akien MRSC

Experimental Officer (NMR)

Professional Role

I run the solution state NMR facility in the Department of Chemistry at Lancaster: currently a Bruker Fourier 300 and an Avance III 400. I also play a supporting role for the solid state NMR facility: a Bruker Avance III HD 400WB and 700WB.

I maintain the instruments and the supporting infrastructure, and provide training and advice on everything from sample preparation through to data analysis. If you have any questions, just ask!
