WebAug 21, 2024 · How TGA works. In thermogravimetric analysis (TGA), a sample is continually weighted while heating, as an inert gas atmosphere is passed over it. Many solids undergo reactions that evolve gaseous byproducts. In TGA, these gaseous byproducts are removed and changes in the remaining mass of the sample are recorded. WebA popular method of performing gravimetric analysis through precipitation where a precipitate is found by adding a reagent to the analyte. The factors that affect the precipitation in a gravimetric analysis deal with the precipitate solubility, the particle size of the precipitate, and impurities present in the precipitate.
