    1. Scope

    This method is for simultaneously determining organically based carbon, hydrogen and nitrogen in coals, cokes, oils and other materials. The detection range for each element is 0.04 to 100 mass-%. Water contained in the samples will contribute to the hydrogen values. Solid samples containing greater than 5% sodium carbonate may be incompletely pyrolyzed resulting in low carbon values.
