What is Ultimate Analysis?

Ultimate Analysis Tests. Ultimate analysis tests produce more comprehensive results than the proximate analyses. SGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference).
