A measured volume of the sample solution is placed in the furnance and electrically heated in at least three steps. A major advantage of the use of furnaces is the small sample volume that is required for an assay. Typically between 5 and 50 μL is used for each assay.In the drying stage the solvent is evaporated from the sample solution by holding the temperature of the furnace slightly above thr boiling point of the solvent. For aqueous solutions the furnace temperature is usually adjusted to110 ℃for 30 s. The temperature in the drying stage should be sufficiently low to prevent spattering.
