    When a sample is dry ashed a fine residue (ash) is often formed. The small particles in the residue are resuspended readily by any air flow over the sample. Air flows are generated by changes in temperature (e.g. opening the furnace while it is hot) or by passing a stream of gas over the sample during heating to assist in combustion.
