Chromium Isotope System: Crush, Acidify, Mass Spec

Caption

It's relatively simple to take a chromium isotope reading on a rock sample. First, crush the sample. Second, dissolve the pulverized rock in acid. Then place the solution in a mass spectrometer, which determines how much chromium 53 and how much chromium 52 is in the sample.
