This method is for the determination of drinking, surface, and saline waters, domestic and industrial wastes. A well-mixed sample is filtered through a glass fiber filter, and the residue retained on the filter is dried to constant weight at 103-105°C. The filtrate from this method may be used for filterable residue. Non-filterable residue is defined as those solids which are retained by a glass fiber filter and dried to constant weight at 103-105°C.
The practical range of the determination is 4 mg/L to 20,000 mg/L.
Samples that have dissolved solids (filterable residue) such as saline waters, brines and some wastes may have a positive interference.
Non-representative particulates such as leaves, sticks, fish and lumps of fecal matter should be excluded from the sample if they are required to not be accounted for in the final result.
