Gravimetric analysis determines the amount of a substance by converting it to an insoluble precipitate, filtering, and weighing the solid. For instance, sulfate in a sample can be precipitated as BaSO4. The mass of the precipitate and knowledge of stoichiometry allow calculation of the original sulfate content. Although time-consuming, gravimetric analysis offers high precision and minimal instrumentation requirements.
