    Abstract

    Modulated thermogravimetry (MTG) was introduced in 1998 by employees of TA Instruments. Since that time it has found popularity as a technique for obtaining activation energies of degradation processes in a variety of materials. The initial work claimed that the repeatability of MTG was superior to that of the Flynn and Wall method. Little information, however, was given concerning the accuracy of the technique, and none was provided concerning its reproducibility. Results reported here test the repeatability claims and explore the questions of accuracy and reproducibility.
