Instrument Details

The LEAP 4000X Si local electrode atom probe provides 3D nanoscale compositional analysis.  Mass spectral data obtained through time-of-flight measurements can be used to identify light mass and heavy mass species (hydrogen out to >1000 Da) with equivalent sensitivity.  The mass resolution is sufficient for distinguishing isotopic abundances.  The instrument features both laser pulsing and voltage pulsing along with a 90 mm to 160 mm variable flight path.
