WiscSIMS Laboratory

WiscSIMS, the Wisconsin Secondary Ion Mass Spectrometer Laboratory, explores new applications of in situ analysis to stable isotope geochemistry. Research in many disciplines can benefit by using the IMS 1280 ion microprobe, a CAMECA large radius magnetic sector SIMS. The dramatic reductions of sample size and analysis spot sizes from 1 to 10 micrometers offer many exciting, potentially revolutionary, research opportunities.

WiscSIMS home page will be renewed fall 2021. For detailed information of the laboratory, access information, and sample preparation guide, please download pdf files linked below.
