The data show consecutive preparations in the same fusion machine done on the same day, except of where it is mentioned ...
Crucibles and casting dishes are needed to produce fused beads with the VITRIOX ELECTRIC and VITRIOX GAS fusion machines. A special platinum and gold alloy with a composition of 95% Pt and 5% Au is commonly used. ...
The analysis of materials containing chlorine with XRF is a continuous challenge, because chlorine displays high volatility during borate fusion. This leads to poor repeatability with conventional fusion ...
The analysis of iron ores using fused bead preparation is well described in ISO 9516-1. This report will demonstrate the performance of our VITRIOX electric for the sample preparation of iron ores according the international standard ...
Homogenization of the melt is an important aspect of sample preparation for X-ray fluorescence analysis using fusion. Whether the fused bead breaks or remains mechanically stable after cooling, depends largely on the homogenization. Once a stable fused bead has been obtained, it is only possible to judge if the sample is truly homogeneously dissolved in the flux by way of analytical precision ...
Sample fusion of non-metal solids is conducted routinely in daily analytical life. This report presents the use of quartz crucibles as an alternative to platinum crucibles for automatic fusion ...
Here it is important that the sample is fused with the borate to 100% and that a homogenous fusion bead is produced. FLUXANA's electrical fusion machine guaranties both of these requirements. ...
The analysis of materials containing chlorine with XRF is a continuous challenge, because chlorine displays high volatility during borate fusion. This leads to poor repeatability with conventional fusion ...
