ABSTRACT:
A method for controlling a thermogravimetry experiment and for quantitatively determining kinetic constants for decomposition or volatilization reactions using periodic forcing (modulated) temperature functions. A temperature program having a linear part and a periodically varying part superimposed thereon is applied to a sample in a thermogravimetric analyzer. The resulting mass signal is deconvoluted, or separated, into one or more deconvoluted signals.
