红外碳硫仪测定铁矿石中高含量硫的探讨

Discussion on Determination of High Sulfur Content in Iron Ore by Infrared Carbon-Sulfur Meter

探讨了用红外碳硫测定仪测定铁矿石中高含量硫时,称样量的多少对样品分析过程中燃烧效率的影响,使测定的硫不稳定。分析过程中标样的选取对测定结果起着决定性作用。

The influence of sample weight on combustion eff iciency in sample analysis was discussed when high content of sulphur in iron ore was determined by infrared carbon and sulphur analyzer,which made the determination of sulphur unstable.In the process of analysis,the selection of standard sample plays a decisive role in the determination results.
