It is capable of detecting isotopes of every element in the periodic table at ppm or ppb levels depending upon the element. Typical applications include trace or light element mapping and spatially resolved isotopic ratio measurements.
It can be an extremely powerful method for understanding the dynamics of processes by stable isotope labelling in materials across all scientific disciplines. It is also one of the few techniques available that can spatially resolve hydrogen distributions.
It can be an extremely powerful method for understanding the dynamics of processes by stable isotope labeling in materials across all scientific disciplines.
However, it is not particularly useful for the quantification of trace elements because matrix matched standards are required to convert the measured ion signal into a concentration. It is also one of the most complicated instruments in the Royce toolkit and is therefore not amenable to “quick look” types of experiments.
50 nm with Cs+ beam (for electronegative elements), 200-300 with O- beam (for electropositive elements)
ppm to ppb, depending upon element
6 movable detectors and 1 fixed detector allow for parallel acquisition of 7 masses
Analysis Chamber vacuum
~5e-10 mbar (samples must be high vacuum compatible and flat)
