Metal Alloy, Industrial and Geological  Reference Materials                      

ARMI | MBH  is an ISO 17034 accredited manufacturer of high quality metal alloy reference materials under the IARM and MBH brands and has the capability to source reference materials from around the world.  Metal alloy CRMs and RMs, non-metallic standards, and industrial and geological reference materials are available to cover a broad range of applications. 

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

Inert gas fusion method is used to analyze the material. A small sample of the material, usually under a gram, is weighed and placed in a graphite crucible. Next, it is burned in a stream of inert gas. Argon or nitrogen is used for hydrogen analysis, while helium is used for the oxygen/nitrogen analysis.

Typical Matrices: Steel-Pins-for-Oxygen-Nitrogen, Chips-for-Carbon-Sulfur-Nitrogen, Zirconium-Pins-for-Hydrogen-Nitrogen-Oxygen, Steel-Pin-for-Hydrogen, Titanium-Pins-for-Hydrogen-Oxygen-Nitrogen, Titanium-Zirconium-Pins-for-Hydrogen-Carbon, Copper-Pins-for-Oxygen-Sulfur, Iron-Powders-for-Oxygen-Nitrogen, Hydrogen-in-Carbon
