Comment on the interpretation of dynamic derivative thermogravimetric curves.
A comparison is made of dynamic thermograms and their derivative curves, and the significance of the various features of these curves is discussed. The designation of peak temperatures on derivative curves as decomposition temperatures is shown to be wrong. An illustration is given of the value of a derivative thermogram in disclosing the existence of successive overlapping reactions that might escape detection on an integral thermogram.
