NanoSIMS 50 & 50L Instrumentation - Intercovamex

NanoSIMS 50 main options
NEG. Normal incidence Electron flood Gun for the analysis of strong electrical insulators in Cs + with negative
secondary ions, when gold coating method is not sufficient, at high beam current.
SED. Secondary Electron Detector. Works only in negative secondary polarity with cesium primary ions. Can
give nicely contrasted topographical images for illustration and sample visualization.
Full-MDA. Motor Driven Apertures. Automation of diaphragms, apertures and hexapole for an easier
operation, a better reproducibility and a higher throughput.
Z-motor. Automation of the sample stage Z-axis. Allows to re-adjust the sample Z position for sub-permil
isotopic ratio reproducibility in geochemistry, in automated or chain acquisition mode.
Geo-Faraday. Low-noise FC electrometer for geological applications in single FC-EMs mode.
Dual-Faraday. Special trolleys #1 & #2 derived from NS50L design, equipped with both E.M. and F.C.,
allowing FC-EM or FC-FC acquisition modes. Includes thermostated FC preamplifier chamber with
intercalibration. Keeps the standard FC attached to the the lower mass side of trolley #1.
NMR H/D. Additional NMR probe to ensure the best long term stability for hydrogen-deuterium measurements
(the B field is too low for the standard NMR probe to improve the stability compared to the standard Hall probe
regulation mode).
