This method is for the determination of total residue from drinking, surface, and saline waters, domestic and industrial wastes. A well mixed aliquot of the sample is quantitatively transferred to a pre-weighed evaporating dish and evaporated to dryness at 103-105°C. Total residue is defined as the sum of the homogenous suspended and dissolved materials in a sample.
The practical range of the method is from 10 mg/L to 20,000 mg/L.
