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® Pre-Fused FusionFlux® Formulations. Attributes of Pre-Fused FusionFlux® Formulations 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% 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. Chemplex 光譜認(rèn)證®預(yù)熔合熔劑配方規(guī)格：
