Automated Flux Dosing

Dextra automates the precise dosing of lithium borate flux used in XRF fusion workflows. Users can program target weights and tolerances, and the system dispenses flux into multiple vials with milligram-level accuracy.

  • Batch-based weighing: program and process up to 25 samples in a single run
  • High-precision dosing: delivers flux with tolerances down to 1 mg
  • Automated operation: eliminates manual intervention and calculation

This ensures consistent dilution ratios during fusion, directly improving analytical repeatability and data quality in geochemical analysis.

Automated Flux Dosing in Geoscience

In XRF-based geochemical analysis, accurate flux addition is critical to achieving homogeneous fusion beads and reliable elemental data. Even minor deviations in flux mass can lead to dilution inconsistencies and analytical error.
Dextra addresses this by standardising the flux weighing step, eliminating operator variability and ensuring each sample is prepared under identical conditions. This is particularly valuable in high-throughput environments where reproducibility, data integrity, and turnaround time are essential.
