Fusion Machines for XRF Sample Preparation — VITRIOX by Fluxana
A fusion machine melts the powdered sample with a flux into a homogeneous glass bead, removing particle-size and mineralogical effects so XRF results are accurate and repeatable — a standard step in cement, mineral, ceramic and glass analysis. Fluxana makes both electric and gas-fired fusion machines.
VITRIOX fusion models
VITRIOX ELECTRIC
A fully automatic cold-to-cold electric fusion machine, one sample at a time, with 1, 2, 4 or 6 stations.

VITRIOX ELECTRIC 4+
A fully automatic electric fusion machine for high-throughput routine: four samples per fusion, 4–16 in continuous operation.

VITRIOX GAS
A gas-fired cold-to-cold fusion machine running up to six positions at once, with low power consumption.

How Sample Fusion Works
The machine melts the sample powder with a flux at high temperature in a crucible and casts it into a homogeneous glass bead. This removes particle-size and mineral-structure effects, so XRF results are accurate and repeatable.
- Homogeneous — the glass bead removes particle-size and mineral-structure effects.
- Accurate and repeatable — suits multi-mineral samples where pressed pellets give less accurate results.
- Calibrate with synthetic standards — make calibration beads from synthetic standards.
- Electric or gas — VITRIOX ELECTRIC and 4+ are electric; VITRIOX GAS is gas-fired.
Applications
What Is Fusion Used For?
Ores, Minerals and Cement
Multi-mineral samples where particle size and mineral structure disturb the measurement, including clinker, raw materials and finished cement.
Ceramics, Glass and Refractories
Ceramic raw materials, kaolin, sand, glass products and refractory materials.
Calibration Standards
Prepare calibration beads from synthetic standards for your XRF.
When to fuse
Fusion versus pressed pellets
Fusion suits
- Highest accuracy and a fully homogeneous sample
- Multi-mineral or multi-phase samples where particle size and mineralogy disturb the result
- Calibration with synthetic standards
- Volatile-element analysis or quartz crucibles (model dependent)
Pressed pellets suit
- Screening and QC where speed and low cost per sample matter
- Samples that are already homogeneous
