Carbon black is made from coal tar and various petroleum tars from the cracking process. Carbon black is a crystalline form of carbon with very high surface area to volume ratio and is used mainly as a reinforcing filler in tires and used to strengthen engine hoses and gear belts. It is also used as copier toner inks and as pigment in polymers. The elemental characterization of the carbon black is critical to ensure proper quality of the various products. To meet this industry need Applied Rigaku Technologies offers Energy Dispersive X-ray Fluorescence (EDXRF), ideal for the fast and simple analysis of carbon black and related products. Innovative design using 60kV tube and high resolution detector 500,000+ cps detector throughout provides sensitivity for trace measurements and low detection limits. Simple, intuitive software flow makes the NEX DE an ideal EDXRF tool for the elemental identification (Na-U), screening and characterization of raw materials and final products. Simple to operate, the NEX DE is used by the non-technical operator and researcher alike.
