XRF-FUS-09
Multi-Element & Geochemical Analysis
XRF Whole-Rock Major Oxide Analysis (Fused Bead)
Precision whole-rock geochemical characterization of silicate, carbonate, and iron formations using lithium borate fusion discs to eliminate mineralogical matrix effects.
Detection Limits
0.01% – 100.0% Major Oxides
Turnaround (TAT)
Standard: 4-6 Working Days
Sample Requirement
2.0g pulverized sample pulp
Quality Framework
ISO/IEC 17025 Compliant
Analytical Overview & Methodology
Whole-rock geochemical characterization demands complete dissolution of resistant minerals like zircon, tourmaline, and chromite. Our Fused Bead XRF Analysis (XRF-FUS-09) melts the sample into an amorphous glass disc, completely removing grain size and matrix effects.
