连续光源原子吸收光谱仪--划时代的技术革命

长期以来，原子吸收使用的光源主要是空心阴极灯，即锐线光源原子吸收，每分析一个元素就要更换一个元素灯，使原子吸收分析的速度、信息量和使用的方便性等方面受到了限制。商品化连续光源原子吸收多元素分析一直是分析工作者的一个长期梦想。详细介绍了由德国耶拿分析仪器股份公司(Analytik Jena AG)成功研制的世界第一台商品化连续光源原子吸收光谱仪(contrAA)的关键技术、主要技术指标、显著特点和发展前景。     

Iron Ore Sintering: Process

Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace. The process has been widely studied and researched in the iron and steelmaking industry to know the best parameters that allow one to obtain the best sinter quality. The present article reviews the sintering process that the mixture follows, once granulated, when it is loaded onto the sinter strand. There, the sinter mixture is partially melted at a temperature between 1300-1480°C and undergoes a series of reactions that forms the sinter cake to be loaded into the blast furnace to produce pig iron.     

Low pressure mercury–argon electrodeless fluorescent lamp simulation using the finite volume method

A finite volume model of a low pressure Ar–Hg electrodeless lamp with external coils is established. The physical configuration is similar to the OSRAM/ENDURA 70 W lamp. A Maxwellian energy distribution is assumed. Two dimensional behaviors of the most important plasma parameters such as the electron density, the electron temperature and the most important mercury states are discussed. Results are in good agreement with former studies and the general understanding in this area. Also, the influence of the argon pressure is studied. Based on the simulation, the population of the main resonance state, Hg (6³P₁ ) depends on the argon pressure and the optimized value is about 300 mTorr.
