Infrared carbon and sulfur analyzer is a kind of instrument for analyzing the content of carbon and sulfur of non-ferrous metals, ferrous metals and other substances. The analysis of content of the carbon and sulfur by Infrared carbon and sulfur analyzer is accurate and fast with a high sensitivity.

 

Tungsten granule is a rare refractory metal, and it is located in VIB sequence of the sixth cycle in the periodic table.  Tungsten granule is made by tungsten processing. Tungsten is the hardest melting metal, its melting point is 3380 ℃ with a high purity above 99.95%. As the additive of Infrared carbon and sulfur analyzer, tungsten granule can enhance the accuracy and the stability of the decomposition results. When analyzing, tungsten granule can also have function in heating and catalyzing, which can greatly improve the efficiency of Infrared carbon and sulfur analyzer. Tungsten granule can be oxidized easily at a high temperature, and release large amounts of heat quickly. In most cases, tin is mainly applied to reduce the effect of insufficient fluxing by tungsten granule and improve the stability and accuracy.

 

Tungsten granule can release carbon and sulfur sufficiently by reducing the melting point of combustion. The size of tungsten granule should within 0.84 and0.42, the porosity is about 15%. It can avoid the interference of oxygen. This type of tungsten granule can also accelerate the burning of oxidation and reduce adsorption of surface.
