Lab equipment

The SHRIMP-RG is at Stanford University as a result of a partnership between the U.S. Geological Survey and Stanford Doerr School of Sustainability. The laboratory has been jointly operational since 1998, supporting scientists and students from the USGS, Stanford, and external visitors from around the world who visit the laboratory to analyze specimens for a variety of scientific research objectives.

We are committed to making SHRIMP-RG available to the scientific community and seek projects that require spatially resolved measurements and benefit from SHRIMP-RG's unique combination of high secondary ion transmission and high mass resolving power.

Stanford-USGS SHRIMP-RG — 25 years and still going strong

The SHRIMP-RG ion microprobe has been operational at Stanford University since 1998 and continues to provide high-resolution geochronologic and geochemical data to many researchers for a wide variety of investigations.


All SHRIMP-RG data can now be uploaded to

All U-Th-Pb and trace element data produced by SHRIMP-RG that has been reduced in SQUID-1 or SQUID-2 is now suitable for upload to This is important for data management, archiving, and optional release of data acquired during NSF-supported research.
