SIMS Microprobe for Isotopic and Trace Element Analysis at High Spatial Resolution The NanoSIMS 50L is a unique ion microprobe optimizing SIMS analysis performance at high lateral resolution. It is based on a coaxial optical design of the ion beam and the secondary ion extraction, and on an original magnetic sector mass analyzer with multicollection. The NanoSIMS 50L delivers simultaneously key performance metrics that can only be obtained individually with any other known instrument or technique: High analysis spatial resolution (down to 50 nanometers) High sensitivity (ppm in element imaging) High Mass Resolution (M/dM), Parallel acquisition of seven masses Fast acquisition (DC mode, not pulsed) Analysis of electrically insulating samples without problem. And thanks to recent improvements, isotope ratio reproducibility of a few tenths of permil can now be achieved. Extended fields of applications Microbiology: The NanoSIMS 50L opens new possibilities for coupling phylogenetic identity (with FISH or El-FISH) and metabolic function (using stable isotope labeling) of single cells in studies of mixed microbial communities from the environment.
