The micro-XRF analyzer (Horiba XGT-7200) is used for single point, multi-point (user selected or line-scan), hyperspectral mapping analysis, and transmitted X-ray imaging.  The spatial resolution of the instrument is adjustable by means of computer-controlled switching between the 50 μm and 1.2 mm X-ray mono-capillary guide tube.  Dual vacuum modes (full and partial) allow for solid and liquid analysis.  Partial vacuum analysis keeps the sample at room pressure and the vacuum is applied to the detector and X-ray optics.  The elemental range is from Na to U, and Rh target is used with a maximum tube power at 50 kV and 1 mA.  Some mapping specific details here...
