Dauphas and his associates spent three weeks searching for chromium 54-enriched nanoparticles with an ion probe
at the California Institute of Technology.
He then joined the Spectroanalysis Section of the National Bureau of Standards (now NIST), doing research in the theory and applications of electron and ion probe
Attempts to measure the onset of this elevated efflux during the initial application of hsp70 were frustrated by the interaction of hsp70 with the calcium-selective liquid membrane tipping the ion probe
An ion probe has two parts: a focused ion-beam source for sputtering ions from a small-volume sample, and a mass spectrometer for analyzing sputtered ions.
What roles does an ion probe play in oceanographic research?
With the ion probe
, researchers can search for the best-preserved section of the crystal.
For a precise analysis of nanostructures, a finely focused beam of primary ion probe is expected with very high brilliance.

The new measurements reveal that the concentration of water in the rocks is less than 50 parts per million--below the limit that could have been detected with less sensitive ion probes
