Cosmogenic Isotope Lab

The geochemistry/cosmogenic isotope lab at UND.

We prepare bulk samples for 26Aluminum and 10Beryllium measurement in AMS.
A brief process outline:
-Physical separations (crushing, sieving, density separations with LST)
-Quartz cleaning (multiple/varied acid leeches and ultrasonication)
-Quartz purity checks (Flame Atomic Absorption Spectrometry "FAAS")
-Quartz digestions (hydrofluoric acid) 
-Ion separation (cation and anion chromatography)
-Al and Be precipitation to hydroxide gels (ammonium hydroxide)
-Al and Be conversion to oxides (flamed in quartz crucibles)
-Pack oxides in cathodes for Accelerator Mass Spectrometry
