High Purity Pre-Fused fluxes for X-Ray fluorescence analysis
Spectrometric analysis has become a valued tool in the modern laboratory.
Fusion is used to prepare a wide range of samples for analysis by x-ray fluorescence, atomic absorption, inductively coupled plasma-atomic emission spectrometry and a variety of classical chemical techniques.
Some of the sample types include oxides, sulphides and aluminosilicates. These comprise many of the ores and concentrates in the mining and metallurgy industry.
Samples are mixed with borate fluxes and dissolved (fused) at temperatures between 900°C to 1250°C. The typical lithium borate fusion temperature is 1050°C. The molten glass can be poured into dilute acid for AAS and ICP-AES analysis.
Precise control of cooling is essential to reproduce flat glass discs and to avoid cracking or crystallisation. Phoenix automated fluxers are designed to consistently produce fused beads under accurately reproducible fusion conditions.
The molten glass can also be poured into a casting dish for the XRF analysis.
