Claim Text:
1. A system for determining a kinetic parameter of a sample, comprising: an oven having a heater for heating the sample according to a modulated temperature program, said modulated temperature program having a temperature amplitude and a modulation period; means for detecting a thermogravimetric signal corresponding to a weight of said sample; means for determining a first derivative and amplitude of the first derivative of said thermogravimetric signal as said sample changes weight as a result of being heated according to said temperature program; and means for determining at least one kinetic parameter using the temperature, the temperature amplitude, the first derivative of said thermogravimetric signal and the amplitude of the first derivative of said thermogravimetric signal, but without using a logarithm of a non-exponential function derived from the first derivative of the thermogravimetric signal.
