AN712-THERMOGRAVIMETRY COUPLED TO EVOLVED GAS ANALYSIS TO INTERPRET THE THERMAL DECOMPOSITION OF SALTS OF ORGANIC ACIDS Private content

Thermogravimetry (TG) or Thermogravimetric Analysis (TGA) measure the mass loss or gain of a sample of material as a function of time or temperature when it is heated or cooled under a certain temperature profile. Simultaneous thermal analysis (TG-DTA or TG-DSC) additionally allows qualifying or quantifying the corresponding heat effects. But these two methods do not allow for the definite identification of the products of the studied reactions or decompositions and for the determination of their chemical mechanism.
