✓Submission Requirements
- Representative sample of the material to be analyzed, correctly labeled.
- Dry and homogeneous material.
- Required mass: approximately 100 g per sample.
- Particle size appropriate for the analysis.
- Indicate sample type (feed, concentrate, tailings, synthetic, etc.) to define the preparation protocol.
- Inform if the sample is water-soluble or has reactive behavior.
- Samples are prepared as briquettes (polished sections) in the laboratory.
!Technical Limitations
- Resolution dependent on particle size and analysis conditions.
- Difficulty differentiating phases with similar chemical compositions.
- Sensitive to briquette preparation quality.
- Soluble, unstable, or reactive materials must be evaluated on a case-by-case basis.
- Results depend on the mineral phase list (SIP) used.
- Detection limit ~0.1 wt%, depending on the material.
- Limited for elements up to Be.
