Abstract
Disclosed are improved methods and apparatus for determining a kinetic parameter of a sample via thermogravimetry. According to the methods, accuracy of the measured parameter is improved and made less susceptible to noise across a temperature range, in particular at near-zero values of the rate of change of the weight of the sample. The disclosed methods avoid taking a logarithm of the first derivative of a thermogravimetric signal related to the sample weight detected during the experiment.
