Method Source U.S. EPA National Exposure Research Laboratory (NERL) [formerly EMSL] Method Number 160.4 Revision Information Issued 1971 Method Name Descriptive Name: Volatile Residue by Muffle Furnace Official Name: Residue, Volatile (Gravimetric, Ignition at 550 oC) Media Media: WATER Subcategory Inorganic Citation Methods for the Chemical Analysis of Water and Wastes (MCAWW) (EPA/600/4-79/020) Method Download Download full method now (PDF file) Summary of Method The residue obtained from the determination of total, filterable or non-filterable residue is ignited at 550oC in a muffle furnace. The loss of weight on ignition is reported as mg/L volatile residue. Scope and Application This method determines the weight of solid material combustible at 550oC. The test is useful in obtaining a rough approximation of the amount of organic matter present in the solid fraction of sewage, activated sludge, industrial wastes, or bottom sediments. Applicable Concentration Range Not Available. Interferences None. QC Requirements None. Sample Handling Preservation of the sample is not practical; analysis should begin as soon as possible. Refrigeration or icing to 4oC is recommended. Max Holding Time 7 days (MCAWW, Table 1). Relative Cost/Effort Less than $50 Sample Prep Method(s) None.
