gravimetric method definition
Gravimetric Methods. Gravimetric methods of analysis are based on the measurement of mass. The two gravimetric methods are precipitation methods and volatilization methods. In precipitation methods the analyte is converted to an insoluble product, filtered, washed and heated. The mass of the resulting residue is determined. In volatilization methods the analyte is heated and the analyte or its decomposition product is collected. The resulting loss of mass is determined.
