Trace Elemental Mapping for Critical Mineral Characterization

Application Note: See how Massbox maps critical minerals like cobalt and rare earth elements at trace levels with mineral-scale resolution, in a single analytical session.

This application note addresses a persistent challenge in critical mineral exploration: fully characterizing an ore deposit's chemistry has traditionally required a trade-off between elemental coverage, spatial resolution, and sensitivity.  

Bulk geochemistry provides the full elemental suite but no spatial detail, while conventional microanalytical techniques offer resolution but cover only part of the periodic table.

Using Massbox's Laser Ablation Laser Ionization Time-of-Flight Mass Spectrometry (LALI-TOF-MS), this note demonstrates how the full periodic table—from Li to U—can be mapped simultaneously with ppm-level sensitivity and micron-scale spatial resolution, with a full mass spectrum captured at every pixel.

Application examples include:

  • Cobalt zoning and trace element correlation in a rock thin section
  • Beryllium mapping to characterize gem-quality aquamarine
  • Rare earth element (Nd) and critical element (Ge) discovery in trace concentrations

The application note shows how Massbox's combination of elemental coverage, spatial resolution, and trace-level sensitivity turns what was previously a multi-instrument, multi-week workflow into a single analytical session under 30 minutes.  

Massbox gives exploration and mining teams the data they need to make faster, better-informed decisions about where to drill and which targets to advance.
