Abstract

The sample of coal is heated at 105 to 110 °C in a stream of oxygen-free, dry nitrogen and the moisture driven off is collected in an absorption tube containing a desiccant. The increase in mass of the absorption tube (after deducting the result of a separate blank determination) is due to moisture in the sample of coal.
