APPLICATION NOTE 45/2022
This paper provides a review on sample preparation by borate fusion and presents a comparison of different heating technologies. High-frequency induction fusion is a common method in industrial and research laboratories. Compared to instruments with gas or electrical resistance heating, induction systems offer substantial benefits including high sample throughput, flexible and rapid change of the fusion temperature as well as low maintenance and operating costs. Furthermore, recent developments allow a precise and accurate temperature control in induction heating which is comparable to the performance of resistance furnaces using thermocouples.
