High temperature combustion, typically induction, is used to determine carbon and sulfur content in a variety of materials, both organic and inorganic. Alpha Resources supports the process by providing ceramic crucibles or ceramic boats as well as a certified reference materials (used in induction analysis of carbon and sulfur).

Typical Matrices: Steel-Rings, Steel-Pins, Chips-and-Powders-for--Carbon-Sulfur-Nitrogen, Tungsten-Carbide, Cast-Iron-thru-Wrought-Iron, Titanium-and-Zirconium-for-Carbon-and-Hydrogen, Copper-Pins-for-Sulfur-and-Oxygen

Coal has four main types, or ranks—lignite, sub-bituminous, bituminous, and anthracite—in order of increasing carbon and energy content. Most of the coal burned in U.S. power plants is bituminous or sub-bituminous coal. A fifth type, called metallurgical, or “coking” coal, is used for steelmaking. Coke is a residue remaining after certain types of coals are heated to a high temperature until substantially all of the volatile constituents have been driven off. The resulting residue is largely carbon, with minor amounts of hydrogen and sulfur.

Typical Matrices: Coal Powder, Coke Powders
