The SIMS lab at DTM, initiated in 1995, houses a Cameca IMS 6F small-radius ion probe and a Cameca NanoSIMS 50L ion probe.  Each instrument is equipped with oxygen and cesium primary ion sources and an electron flood gun for charge compensation.  They are used for a wide variety of applications where spatial resolution is critical, from measurements of volatiles and trace elements on individual minerals and fluid/melt inclusions to isotopic measurements of H, C, N, O, Mg, Si, S, Ca, Ti, Fe and Ni in terrestrial, meteoritic, and extra-solar materials.
