Abstract: GGB-1 bead maker with high frequency induction heating for sample preparation in X-ray fluorescence analysis has been developed. High frequency induction heating and automatic microcomputer control technology were used and the temperature phaselocked loop system was devised. The heating speed and temperature could be controlled by the oscillation current output from high frequency generator, which provided the intelligent and automatic fusing procedure. The molten sample homogenizer was devised, which could swing and spin synchronously and form electric eddy in flux to attain homogenous bead. Based on sample preparation characteristic of XRF analysis, preoxidation process was designed for ore sample analysis. The results from equipment performance testing showed that the highest fusion temperature of bead maker was 1300℃ with temperature fluctuation of ±2℃ and the precision of sample preparation was better than 0.3%RSD（n=11）.
