A high frequency Induction Fusion Machine for Sample Preparation is used to prepare oxidic and metallic samples for X-Ray fluorescence analysis (RAF), ICP and AAS XRF Analytical System. At present, induction fusion method is known as highest degree accuracy sample preparing method in analytical field. Fusion method eliminates the grain effect, matrix effect and mineral effect brought by pressed disc method. Melting fusion of oxidic materials such as ores, slags, dust, minerals, refractories, etc. in special platinum/gold crucibles (95/5%).
The fusion material in the crucible is melted by induction heating. The eddy currents guarantee that the melt has an optimal mix by the so-called bath movement. By that a constant and homogeneous quality of the melt is achieved. Accuracies of analysis and economy with optimal sample quality confirm the high quality of this method with a minimum of elemental losses, which can be rectified. Stirring will be done by a motorized vibrator that can be selectively switched on. The casting tray and crucible are simultaneously preheated by induction through double induction coils. In automatic operation, the temperature will be monitored by pyrometers. By this method of heating oxidic material fused in Pt/Au crucible with temperature up to 1500℃ can be achieved within 8 min.
An Induction Fusion Sample Preparation Unit consists of a high frequency Induction Generator and chiller. The high-frequency generator with protective cover is housed in a robust steel sheet housing. The melting process is well observed through the glass window in the front cover. When the cover is opened, the power will be turned off automatically. A fan evacuates the inner cavities of the two melting units from the rear side to protect the operator.
