The roots of classical gravimetric chemistry can be traced back to ancient alchemy. Modern classical methods include digestion/dissolution of samples, separations such as ion chromatography, precipitation and crystallization, and ultimately isolation of a specific chemical substance for quantitative mass determination. Classical methods are fundamental to the production of standard reference materials due to straightforward traceability to the SI unit of mass (the kilogram) and to accurate atomic mass determinations.
