The Center for Elemental Mass Spectrometry (CEMS) is a core analytical facility and cost center at the University of South Carolina. The focus of our research is geochemistry and chemical oceanography. Plasma-source mass spectrometers are the heart of CEMS. We use these for trace metal and isotope ratio measurements on a wide variety of sample types.
