GPS Division Analytical Resources


Environmental Analysis Center (ESE):  An open-access, user-operated laboratory at the California Institute of Technology. The EAC is based in the Environmental Science and Engineering Program, but is open to all Caltech researchers. Analytical methods available include mass spectrometry, gas chromatography, liquid chromatography, ion chromatography, inductively-coupled plasma mass spectrometry, and capillary electrophoresis. (


Center for Microanalysis: A new research establishment within Caltech's Division of Geological and Planetary Sciences that provides hardware and expertise for microanalysis of geological, meteoritic and synthetic materials. The CMC consists of three major components: A laboratory that houses advanced instruments for in situ chemical and isotopic analysis of solids; a program of instrument and methods development grants to encourage 'in house' invention and innovation of micro-analytical techniques; and a program of graduate and postdoctoral training.
