XRF FUSION FLUXES
SPECTROCERTIFIED ® PRE-FUSED
FUSION FLUXES
HOME The flux fusion process is an effective
and simple method for preparing
powdered sample substances for XRF,
ICP and AA analysis. The method is based on the
dissolution of a sample in conjunction with an appropriate
fluxing ingredient at an appropriate temperature. For direct
XRF analysis, the molten mixture is cast into glass-like beads or further processed for ICP or AA solution
analysis. The most effective fluxing agents are lithium borates as represented by Chemplex SpectroCertified ®
Fusion Fluxes.
ATTRIBUTES OF CHEMPLEX SPECTROCERTIFIED ® PRE-FUSED FUSION FLUXES
■ High Density: reduces exceeding the volumetric capacity of crucibles to maintain sample-to-fusion
flux ratio recipes and avert the potential possibility of spill over.
■ High Purity: reduces the introduction of potentially influential foreign element contamination by
selective control of starting material purity and the pre-fusion process.
■ Low Melting Point: assures the dissolution process at effective temperatures but safely below
temperatures of constituent elements considered sensitive to volatility loss.
■ Low LOI: eliminates time consuming accounting for loss on ignition; typically less than 0.03% loss on
ignition.
■ Anhydrous: reduces water content and eliminates the conventional procedure of drying prior to use.
■ Homogeneity: ensures compositionally similar constituent particles for homogeneous melts.
■ Granulation: promotes uniform particle size, configuration and distribution by minimizing the introduction of
“dust” particles to insignificant levels of concern; typically contain less than 0.05% particles less than 100
microns.
■ Diversified Mixtures: offers the flexibility of selecting from assorted mixtures of different melting points to
reduce eutectic melting temperatures of samples and controlling volatile element evolvement.
■ Free-Flowing: facilitates handling manually or with automatic dispensing devices.
