About

The SIGMA Lab is a shared analytical facility in the School of Earth, Energy & Environmental Sciences that includes key capabilities in the areas of radiogenic isotope geochemistry, non-traditional stable isotope geochemistry, and high-sensitivity geochemical analyses. Planning for the laboratory began in 2007 and the first instrument arrived in Fall of 2009. The lab constitutes the primary research tool for a number of SES faculty, and provides critical analytical support via collaboration with a broad spectrum of additional users from throughout Stanford University.

Mission Statement

The SIGMA Laboratory is a key analytical component of the closely affiliated School of Earth, Energy & Environmental Sciences laboratories. Collectively the laboratories uniquely enable the study of Earth’s dynamic history, its resources and environmental changes. The array of next generation equipment in The SIGMA Laboratory includes a triple-quad ICP-MS (Agilent 8900) with a laser ablation intake system (AS RESOlution laser system), a multi-collector ICP-MS (Neptune Plus), and a specially designed Picotrace metal-free low particulate clean laboratory.

The primary mission of The SIGMA Laboratory is to produce high quality isotopic and trace element data. The laboratory also provides training for the next generation of scientists through detailed instruction of students and postdocs. The laboratory is open to collaboration with all members of the Stanford community.
