Spectrocertified® Pre-Fused Fusion Fluxes
The flux fusion process is an effective and simple method for converting powdered samples into glass-like beads for direct XRF analysis or ICP and AA dissolutions The method is based on dissolving a sample with an appropriate fluxing ingredient and temperature. The most effective fluxing agents are lithium borates as represented by SpectroCertified® Pre-Fused Fusion Fluxes.
Attributes of 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 selectively controlling the 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%.
- 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.
