Quality Control of Coal with Elemental Analyzers

A huge amount of the worldwide traded stone coal is mined in China, USA, Russia and India. Compared to the large amount of mined coal the required sample volume for the characterization of coal, varying from a few mg up to 1 gram, seems unbelievably small. The characterization of coal is important for its quality assessment and further use.
