Control Lab (ERB-5116)

The hub of activity in the IGL is found in ERB-5116, where mass spectrometry control, data reduction and analysis take place on three enterprise computing workstations. The room also houses three optical petrographic and stereo-zoom microscope workstations for mineral hand-picking, optical photomicroscopy, and the preparation and polishing of mineral grain mounts. The IGL control laboratory also has direct access to the ERB-5114 mineral separations laboratory, and the ERB-5118 wet chemistry clean laboratories.
