Option
of undecomposed sample material which now
accelerates its rate of decomposition. As in the
case of too high a ramp rate, the increasing
temperature causes the remaining sample to
quickly decompose which raises the rate of
weight loss (%/minute) to a high level and either
triggers another isothermal hold period or shows
up as a backside shoulder on the weight loss
curve.
An example of using stepwise isothermal
heating is shown in the following “Hi-Res
TM
TGA Examples” section.
