31-1000: FusionFlux® Formulation Lithium Tetraborate 100% (Li2B4O7); 2.2lb (1Kg)
Chemplex® FusionFlux® formulations are made from high quality borate materials, pre-fused to ensure a uniformed mixture that is used to obtain consistent results. Choose the formulation that best suits your sample for optimal fusion results.
• Multiple formulations and low melting points
• Highest purity
• Non-wetting Agent pre-fused in the FusionFlux®
• Uniform particle size
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® FusionFlux® Formulations.
Attributes of FusionFlux® Formulations
Pre-Fused: 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% 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.
Non-wetting agents: (NWA) help reduce the surface tension of the sample solution and make it less prone to sticking to the platinum ware. Each sample does not require a lot of non-wetting agents and Chemplex® FusionFlux® formulations are available with the preset concentrations of the Non-wetting agent. It is highly recommended to use non-wetting agents to lengthen the platinum ware life.
