The method uses a high-frequency induction furnace as a heating source, and uses ceramic crucible as a container for burning samples; in order to effectively detect carbon and sulfur in the sample to be tested in high-purity oxygen, it is necessary to add assistance. A flux that helps the sample melt.
随着生产技术的不断进步， 分析水平的提高， 在材料的碳、 硫分析中需要 使用多元助熔剂。 如钨， 锡， 铁， 铜， 钨铁， 钨锡， 硅钼粉， 五氧化二钒等多 元助燃熔剂。 现有技术中， 当用到三元或三元以上助熔剂时， 一直是将三元或 三元以上助熔剂分别加入装有样品的坩埚中， 使得该三元或三元以上助熔剂在 坩埚中按加入的先后分层或分堆堆积， 每次分析难以按技术要求均等加入， 配 比效果均匀性差， 不仅在燃烧时产生的粉尘量相对较大， 还影响了熔融效果； 再则， 通常将三元或三元以上助熔剂用手工分多次加入， 其加入量的累积误差 较大， 也对碳、 硫分析的精确度造成不利影响。  As production technology continues to advance and analytical levels increase, multiple fluxes are required for carbon and sulfur analysis of materials. Such as tungsten, tin, iron, copper, tungsten iron, tungsten tin, silicon molybdenum powder, vanadium pentoxide and other multi-component combustion flux.

In the middle of the addition, the layers are piled up or piled up in layers, and each analysis is difficult to be added according to the technical requirements. The uniformity of the proportioning effect is poor, not only the amount of dust generated during combustion is relatively large, but also affects the melting effect; The addition of ternary or trivalent fluxes by hand is added in multiple times, and the cumulative error of the addition amount is large, which also adversely affects the accuracy of carbon and sulfur analysis.
