Other Labs
“Clean” lab
This 800-square-foot lab is used for the separation of elements out of natural samples. This lab approaches a Class 100 clean lab, and has no exposed metal surfaces.
“Dirty” Lab
For some wet chemistry, mineral separation and preparation of samples for stable isotope analyses.
Laboratory for “dirty” chemistry
Also for mineral separation and thin section equipment.
Laboratory for light isotope sample preparation
Including two vacuum lines for preparation of various samples for carbon, oxygen and hydrogen isotopic analyses.
