These findings bear out good correlation between the muffle furnace method and microwave LOI testing, and existing AFS specifications will likely be applicable to either method.
The volatiles test differs from the LOI in that a lid is placed on the crucible and the muffle furnace is set at 1200F.
Using the tongs, the covered crucible containing the sample is transferred to the muffle furnace. The crucible must be placed directly under the tip of the thermocouple, where the temperature control of the furnace is most accurate.
