Ash content in coal

AppNote 1378: the measurement of predicted ash content in unburned coal is demonstrated.

Background

Ash consists of the metal oxides and heavier elements that remain after burning removes the organic, gaseous and volatile components. Coal quality and pricing in part depends on the ash content of the coal, and so predicting
ash in coal before burning is important in many areas of the industry. EDXRF offers a fast and simple low cost method of predicting the % ash content in coal before it is burned.
