Custom X-ray Flux

Depending on the application, borate fluxes are not always the most suitable solution.

  • Lanthanum based fluxes
  • Sodium based fluxes (sodium tetraborate)
  • Fluoride based fluxes

We can make all X-ray Flux formulations to any customer requirement.  Please contact us and let our dedicated staff assist you in meeting your specific X-ray Flux needs. XRF Scientific have developed internal standard fluxes which have been shown to give very high precision results for the analysis of nickel, iron ore and copper. In some instances, the use of internal standards can eliminate the need to carry out high temperature “loss of ignition” with significant cost and time benefits.

Oxidizers

Oxidizers are added to the flux to help ensure complete oxidation of the sample before fusion takes place.

  • Lithium nitrate oxidising agent 1 – 10%
  • Sodium nitrate oxidising agent 5 – 20%

Release Agents

Release agents increase the surface tension of the mix. They help the bead release from the platinumware and so prolong its life and reduce cracking.

  • Lithium bromide release agent 0.1 – 1.5%
  • Lithium iodide release agent 0.1 – 1.5%
  • Potassium bromide release agent 0.1 – 1%
  • Ammonium iodide release agent 0.1 – 1.5%

XRF offers a range of fluxes for internal calibration purposes. These fluxes allow the analyst to compare the known quantities of added standard with the analyte of interest.

  • Terbium for Iron Ore
  • Thulium for Nickel
  • Tantalum for Copper

They are particularly useful where bead curvature is problematic and can in some cases remove the need for LOI.
